Neophytos -- the problem with keeping the ArsDigita name is that it's causing significant brand confusion. ArsDigita has created essentially an entirely new platform, with new functionality. The goals of their new project are radically different than those of the OACS.
So while an homage to history is nice, in this case it may really confuse anyone new to the community.
As an aside, "agora" is already being used ( http://www.w-agora.net/ )
and when i hear it, i immediately think of "agoraphobia". I guess that's my own problem.
