If my supposition of the discussion that has been ongoing is correct, and mind you that this is only my supposition as one
of the developers of phpBB2, I don't speak for the rest of the team... However if this is too fall under the Umbrella of the phpBB Group, like has been discussed would be the preferred method, then it would basically have a core group of developers which would be more or less "assigned" to work on it... Some of these might be some of the phpBB2 Dev team who are interested in this project... and it will most likely include others who would be "dedicated" to the portal side of the project...
This is the project as I see it anyway..
