Hang in there, Dan.
The best guide to creating Python Products that I have seen is in the fairly new book Zope Bible. Last time I looked, Amazon had it marked down from $50 to $35.
Regarding ZClasses -- I did a moderately big project (email newsletters) in Zclasses, and now I'm rewriting it as a Product. Wish I had just done a Product from the
beginning. A fairly strong case against ZClasses
was made on this list last week, in the posting "ZClasses Must Die".
The wonderful thing about Python Products is that they are Python. Get the Zope Bible, and it will show you all the incantations you need to wrap up your python
application in the Zope persistence and web
