Desura

Certainly an option. I personally won't register there (slightly weird ToS, mandatory "Gender" field in the signup form - WTF?). However, if someone from the dev team wants to do that, if any publisher agreements and such fit with AC's license, and so on. I haven't been able to find said agreements anywhere - I hope you don't have to sign an NDA before you get to read them :P

Also, they seem to be adding games by themselves - I know this was the case with Red Eclipse, and I guess it's the same with Sauerbraten.
