SUP does *not* scan the whole tree for each client!
The client says when it did it's last update, and the server has a
database about which file was touched when. It then sends any files that
are newer than the client's timestamp. You only need to scan the tree once
after updating your SUP server.

Updating the SUP database on demand (e.g. CVS commit mails, or SUP
output) would indeed be nice. Shouldn't be too hard to hack. :)
