I just read through the link you posted and, from what I can tell, the ps3 builds there are based on Chocolate Doom. Like Odamex, Chocolate Doom uses SDL and is therefor very portable. Unfortunately for you, I don't believe anybody on our development team has a PS3. However, maybe you can convince the developer of the current PS3 track to switch his development track to Odamex.
Odamex features much of the same compatibility as Chocolate Doom but also comes with the obvious multiplayer features as well as some other advanced features (Boom and limited zdoom 1.22 support for custom wads). The engine already features a robust joypad setup.
Odamex has already been ported to the XBox by our own team and there is currently a Wii port in development as well. We'd be very interested to see work on a PS3 port begin but cannot devote any internal resources to it at this time.
