That's the plan, but I wanted to see what igi and other community members think about it first. I wouldn't want to start or maintain a fork.
Having the data in a wiki would not change the path to discovery, nor would it limit discussion (especially with some kind of a feed to the forum).
If it will be succesful, it would hopefully reside in the same place as the current IESDP, so I see no random-dumb-webpage problem. (if you were refering to what gemrb's address resolves to: this is just the end host, since sourceforge had crappy project web space until this year; the site is accessible through the simple gemrb.sf.net/gemrb.sourceforge.net subdomain)
