I think with many of the Wikiversitys there is still the challenge to find what is it for. I would propose that Wikiversity could focus on:
(1) collaborative learning in online courses in the P2PU style (http://p2pu.org/ ), just being more community-driven and open, and
(2) building interactive self-study courses (computer-based training)
It would probably be possible to start a School of the Wiki Way or something similar *within* P2PU. There is already a School of Webcraft, and now a School of Social Innovation, and School of the Mathematical Future (the latter one I helped start).
At the moment, I don't see a particular reason for Wikiversity to rebuild P2PU infrastructure from scratch, when it could instead be reused to do something cool more quickly and then tweaked with considerable future promise. I know several P2PU courses are using Wikiversity as a place to host some of their content, and perhaps good things would come from a suitable bidirectional channel :)
As for the computer-based training idea: not likely to go from 0 to 8000BPS overnight. Does Wikiversity have a roadmap? If CBT was in the roadmap, it might actually happen ;). Note, in my Ph. D. project I'm working on something related, for mathematics, in the PlanetMath setting.
One thing both P2PU and PlanetMath have in common is that they are not wikis, at least not in the traditional sense, though both have wiki aspects. I've often asked myself what PlanetMath's role is in the "wiki world" of wikimedia. Wikiversity could also ask what its role is in the broader and often non-wiki, or not exclusively wiki, world of online educational communities.
