have there been any single instance of a ROM site being shut down for hosting amiga ROM's?
Getting the TOSEC of the roms is easier then stealing candy from a baby.
I don't see why Eben even should waste time on it, since everyone who would want the roms for the PI would get them easy.
Also: Eben great work with the PI, I got a few and I love them, have been sharing them to friends so we all can work together

I'm still trying to get an Amiga Emulator to build on my Pi, GLES is cause the most headaches right now. More interesting is a direct compile of AROS for the RasPi, which makes a lot more sense than an OS as heavy as Debian 
Add PND support and you can use this UAE4ALL 2.0 on the PI, maintained by EvilDragon from OpenPandora. Just reconfigure the input and it should work on the PI.
