I'd think this bug has a high priority, because I roundup
really needs
a Zope frondend. There are new issue trackers coming up for
Zope and roundup might miss the opportunity to grow a zope
community.

As for the problem of mapping zope users to roundup user,
one idea I have is that you could just map each zope user
that actually
accesses contents of roundup to the roundup user database
when that happens the first time.  Thus it will always exist
even when the user does not exist for zope anymore.
