Hi Sean!

Some of the ones that we've compiled (visible via http://svn.repoze.org or 
http://dist.repoze.org):

repoze.vhm (virtual hosting services)
repoze.retry (retry a request when an exception is encountered)
repoze.tm2 (transaction management, depends only on the 'transaction' module and 
zope.interface, see also http://repoze.org/tmdemo.html ... note that "repoze.tm" 
depends on all of ZODB, "repoze.tm2" depends on only the smaller packages but 
does the same thing, at the expense of not being compatible with ZODB 3.6)

You might also take a look at repoze.zope2 to service Zope/Plone requests via 
WSGI: http://static.repoze.org/misc/developingwithrepoze-zope2.pdf and check out 
repoze.org in general, as your goals seem to closely align with its.
