ATI Remote Wonder
The ATI remote wonder is an RF (Radio Frequency) PC remote. It consists of a handheld remote control and a USB receiver with some software to enable control of almost any application. We've done a bunch of testing with this remote and find it to be really good, with range rivalling 802.11 itself.
The remote wonder is bundled with ATI All-in-Wonder video cards with TV tuners but can also be purchased standalone for around US$40.
There is a big user community that has created plug-ins for the software to enable direct control of different applications, such as iTunes, from the remote. (We are looking into enabling some control of Sirocco functions from the remote also, via a plug-in. More on this soon.
