A quick bit of googling and poking around with files shows that a) it's INI-based, b) it will accept a lot more than just the remote it comes with, and c) it looks to be ridiculously easy to extend. It mostly operates by sending keystrokes to applications. I can easily knock up a VB prog to take said keystrokes and do more fun stuff with them
I have a couple of spare remotes kicking around here, which I've been toying with rigging up to my computer for a few years now. The only problem's been finding a suitable reciever chip, and making it play ball under Win2k (suprisingly hard).
This should be fun.
