[xwiki-users] Wiki with Role-Based Access Control

Hello! I am considering starting development on a Wiki-Platform integrated in a RBAC-framework like PERMIS (http://sec.cs.kent.ac.uk/permis/). This would permit to implement a cooperative document creation/distribution with a need to know / need to share concept on part of or whole pages. XWiki seems to be a good candidate for that. Is there any interest by somebody else on this? Cheers, - Rick
