Well -- I liked using Envy.  I was even happy to see
it in VA Java.

I don't really agree that Envy was that awful seeing
as I found it really invaluable to trace back every 
method accept and know which method version were
attached to each class.  It certainly did have a steep
learning curve to it and when the group I was with
went from just filing out class-categories to Envy it
took us over a month to get really comfortable.

The point I was trying to make, though, is that it was
nice to have the deployment-components and versions
abstracted out as first class objects, so a class
could identify which "package version" it came with..
if it were necessary.  

I'd think that we should certainly include multiple
users in a design and plan, but yeah:  it doesn't add
as much initial value as a robust component and
versioning system.  It would be nice to design the
plan, though, so that if someone were interested in
taking it in that direction a roadmap existed.
