If you decide to buy a Remote Wonder and play around with it, here is a howto for the device. This howto shows you how to set the controller up as a mouse for the X Window System and map it to some keyboard input.

I'm sure than we can talk to this device by other means as well, like the IRMan, so I figure that if I get one I'll try to write a drop in replacement for the pyrman python class so that I can use it in my current software without many changes. You may like to use it with the way the above howto describes to surf the web from your couch using your TV, or any other number of uses you can think of. I'd be glad to help anyone get started with this device.
