Hi Matt,

Perhaps I'm missing some context since I couldn't make it to the
workshop this year, but I sense that we're really getting ahead of
ourselves -- rxosd (at least in the 1.4.8 tarball I received at the
Google hackathon) is neither cache coherent, nor consistent.  Until
we, as a community, have a chance to re-architect rxosd to follow afs3
semantics, and to properly support transactional semantics with regard
to vnodes and the volume package, I think it's premature to talk about
how afs3 should be modified to deal with these namespace collisions.

Regards,
