I'd be willing to work on 0.5 SCM-wise, but I would need some C++ people to handle the client. First thing I'd do (assuming I got someone to work on the client) is fix the server browser, add my VC SCM update, add Steam's version of VC/GTA3 support (somebody said this was a simple check of the game .exe version before I believe so that should be easy), and release that after further testing. Then we'd go from there.
Of course, a VC module for Blue would be a significantly better option in the long run but until somebody decides to undertake that, then 0.5 seems to be our only short-term option.
