Was this brought up in any of the discussions?

I'm not sure if the VPS project pertains directly to what you're
talking about, but perhaps some of the code or ideas from the project
might?

Even if it doesn't, it's still an exciting project that adds a ton of
value to FreeBSD's light-weight virtualization strategy. What do think
about the VPS concept in relation to the current virtualization effort
being put in to jails? It seems to me that recent efforts at
virtualizing kernel-level objects makes VPS the future of FreeBSD's
virtualization, leaving jails as a great way to isolate
applications...
