(Blowing my own horn:) There's a new RevSelect product just released 
yesterday that can help you with this. See Zygodact here: 
<http://www.runrev.com/products/related-software/zygodact>

It doesn't do versioning, which is a somewhat separate piece, but it 
does take care of creating and tracking user registrations for you. The 
manual tells you how to use it to implement trial periods and offers a 
script.
