we've been around this barn a couple of times recently. it's a question
of manpower and knowledge (as is most packaging problems)

as far as I know licensing is fine it's just that making a package set
(minimum xen-core, Dom0, DomU, and some method for creating a DomU
runtime environment) is somewhat problematic.
one thing people have been talking about is using the dom0 filesystem as
shared image base, create an overlay using unionfs and let the
individual domU instances accumulate their own changes (i.e. /etc,
/var/log). packages and security fixes would typically be loaded into
dom0 and become visible automatically through the rest of the virtual
machines.
anyway, that's the theory. I haven't had the time to play with unionFS
but I hope to relatively soon.
