Hi Bennett,

you might also look at Zope (http://www.zope.org/ )
Zope covers an object oriented storage (which can
layout over different storage solutions) with an
application framework and can be programmed using
python and or C. You will find Python a lot faster
then Java for most practical cases, including prototyping.

If you look at activestate.com you will find python plugins
for visual studio as well.

Although there are many products avaiable as plugin for Zope,
you should focus on ZPT (Zope Page Templates) and
the object-relational mapping produced with ZPatterns and
stuff. SQL and other relational databases are as well easy
included and work with transactions if supported by the
particular database.

You probably will like the extensible permission engine built
into zope, since it supports exacly what you want here and may
be even more.

Regards
Tino Wildenhain
