It's not the same Data.fs.  But there is a VHM.  My first connection 
works... If I point a browser at www.blackrockcity.org I get the 
LoginManager's login screen.  It's only when I submit my authentication 
data that I have the problem.

No, I'm using a very old 0.0.1.  Where do I get a more recent version? 
Searches on zope.org and google don't help me.

I'm heartened to hear that you (and others) have this working.  I'll 
start from scratch w/ recent versions and will give it another go.  If 
it all works, I'd love to package the whole kit-n-kaboodle up to help 
keep others from having to go through what I have...
