Answer 1

Since my company does this sometimes (text promotions etc, though our main focus is much much lower level stuff), I figured I should pitch in.

By far the simplest way is to use a service such as Clickatell, which provides a HTTP API, as well as FTP and SMPP amongst others. I don't know how Clickatell deals with receiving messages, however, as we use direct SMPP binds to our local mobile operators for this.

If you are willing to pay for it, you should be able to get an SMPP bind to your local mobile operator, but its often expensive. This would also allow you to purchase your own shortcode.

You may also want to give mBlox or Nextcell a look. A quick Google search will turn up more.

you could also buy a GSM modem, which would allow you to send and receive messages as you normally would with a phone, except through a PC. This usually means you will pay whatever you would with a phone. (In Ireland anyway)
