well, I think it would be best to have both, as
they are complementary to some degree, and IMHO
both, the full virtualization _and_ the isolation
will require a separate namespace to work, I also
think that limiting the isolation to something
very simple (like one IP + network or so) would
be acceptable for a start, because especially
multi IP or network range checks require a little
more efford to get them right ...

I do not think that folks would want to recompile
their kernel just to get a light-weight guest or
a fully virtualized one

best,
Herbert
