*BUMP* It is now!
I've just noticed a Remote Wonder driver for it on their plugins page. I don't have a Remote Wonder (yet) so I can't verify how well it works. Is anyone going to give it a try?
I can verify that Girder is an absolutely fantastic program, once you get to grips with configuring it. I use it with the remote on my WinTV2000 and there's loads of things I can get it to do.
