For anyone who cares about empeg/XM radio integration, I'm going to be giving it a shot. The XM Direct XMD-1000 receiver is essentially a vanilla serial interface with a "published" (reverse engineered) protocol, and since there ends up being a lot of overlap with work I did for emphatic, I shouldn't have too difficult a time getting something fairly usable working.
The hardest part will probably be getting my cross-compiling environment running again and making sense of my old code, but stay tuned here for updates.
Also, I know several people talked about getting this going before, so if any of you did get there, please let me know before I duplicate your effort.
