Can I Show The Source SMS Phone Number?

Is it possible to send an SMS or MMS message from a server through a service such as Twilio and set the source 10 digit number as desired?
For example, a delayed message system where someone wants to send a text at a scheduled time, they would enter their phone number, the message, destination number and target delivery date & time.
That information is stored on the server, then, at the specified time, sent through a service such as Twilio. The desire is the recipient should receive the message just as they would have if it was just sent by the sender direct.
The desire is to allow the recipient to respond back to the originator of the scheduled message directly as if it was live in real time and not delayed.
Twilio developer evangelist here.
With Twilio it is only possible to send SMS messages using a Twilio number that you've bought or an alphanumeric sender ID, that is a string up to 11 characters long that starts with a letter.
Spoofing numbers or business names is not allowed.

Deliver SMS messages to Danish numbers which are roaming on foreign networks

I'm searching for a SMS gateway to deliver SMS messages to Danish numbers which are roaming on networks in USA and other countries.
You can use Danish provider e-mail address.
For example to send SMS to Bell mobility user is required to use:
[10digitnumber]#txt.bell.ca (Bell and Solo)
Twilio supports sending to Danish numbers http://www.twilio.com/sms/international Be sure to read the FAQ though.
[Full disclosure: I work for Twilio]
Bear in mind that, as long as you find a service which allows you to send sms messages to the Danish networks, it should not matter if your recipients are currently roaming abroad or using their phones inside the country. This consideration should be abstracted from you by the mobile phone companies.
bibob.dk has a webservice which can send sms to danish numbers. Bibob is a phone service company, so if a normal cell phone can send sms to amerika, bibob should also be able to. Of course you need to buy a sim card to use the service.

Replying to an SMS sent from a modem of SMS service?

I am trying to implement my own theoretical SMS web service (just to understand how this stuff works, I have posted a few other related questions, I think this is it).
Set up a PC. It takes requests from a website I make to send out SMS messages: a user-entered destination phone number, and a user-entered text message
I get a GSM modem, or just a GSM phone. I connect it to the computer.
I get a service plan from Verizon or whoever, some sort of unlimited SMS messaging plan.
They give me a SIM card, which has my unique phone # attached to it (ex: 555-5555). I stick this in the GSM modem.
I get some application (like Kannel) which handles interfacing with the modem and sending out the messages from my machine.
Now users can visit my theoretical website, enter a phone # and message. I grab that data, forward it to Kannel. Kannel interacts with the modem, passing it the data for the message. The modem interacts with the carrier network I signed up with, and broadcasts the actual SMS to it. The carrier network handles routing the message to the actual destination.
This is my understanding of how it works. Now the recipient of this text message will see this message pop up on their device from my modem's number (555-5555). In fact, all the thousands of people using my service will all see the same origin phone number.
If that's so, how do these 3rd party SMS applications give people unique #s for replying to messages they send out?
For example, when I sign up for one of these 'free' SMS services on iPhone, they assign me a unique user ID, like '123'. My friend is on a normal AT&T phone plan. He can send an SMS addressed to '123', and somehow I will get the message. How does AT&T know to route that to this third party service? I can't imagine that they would somehow get a new SIM card with a unique phone number per user that signs up for their service!
Thanks for all your help.
Thanks
The cell network carriers (e.g. AT&T, Verizon) actually rent out custom phone numbers (called "short codes") to 3rd parties to use.
You usually can't acquire these short codes directly from the carrier, but you can go through a 3rd party company to rent the short code. I've worked with companies like MBlox and OpenMarket to use carrier short codes. These companies are sometimes referred to as "SMS/MMS messaging aggregators," because they aggregate messaging services across multiple carriers and offer them to people/companies like you. Most of the time the aggregator will expose some sort of API (SOAP/XML or binary protocol) to access the messaging services to send and receive messages.
There may be other ways to do it, this is just my experience.
I think your comment at the bottom of your message is misleading.
Your friend probably doesn't send a message to "123" infact he probably sends "123 hello george" to a central number, which in turns routes "123" on to you, behind the scenes.
FWIW, mobile messages can appear as though they come from anything (including, for example, a word, and not a number).
Your general underlying assumption as to how gateways work (acquiring simcards) is accurate enough.
