Yep.

FWIW, I don't see background groups as such a big deal.
For example, you could:

1) Stick them under the "stack" folder.
2) Store as a property all of the cards they belong to (for regular 
groups, just 1 card)
3) Whenever someone asks to check out a card, expand the underlying 
CVS/Subversion command to also check-out the groups on that card.

Ditto for the objects in the group.

Granted, it doesn't make for a very nice _looking_ filesystem 
representation, but I assume you would never see any of this since a 
Rev GUI would sit on top of it.
