Exactly. One could give access rights on parts of the wiki with rules such as
<http://xwiki.org/OSSGTP/> can only be edited by members of the <http://www.ossgtp.org/members/#ossgtp> group and their friends.
So at <http://www.ossgtp.org/> there would be a foaf:Document describing the current members, which could be updated periodically. Xwiki.org would get that document every so often (or it could be pinged on changes).
One can imagine a lot of different scenarios....

Those are use cases for foaf+ssl, and I think XWiki is an Operating System, with aim to replace emacs, so yes you can do whatever you want ;-)
