we had Klaus at the DevSummit in Karlsruhe and he gave a talk at
EuroBSDCon as well.  See the wiki and the 2010.eurobsdcon.org web
page (thought the material should be on his weg page as well).

So, yes, we are talking to him, even though I got busy the last weeks.
As he's piggybacking on VNET/VIMAGE and there'll me more things he and
we'll do, there's certainly code going to be shared (I would hope).
