No. CVSup is only a different tool for getting updates. Greg's issue
is the same regardless of whether you use rsync, CVSup, ftp, sup...

(As long as it ends up in a local CVS repository.)

I'm not certain I understand the issue either, but I believe a relevant
question is whether you ever upgrade a vendor branch in your local
repository, by grabbing a newer version and importing it.

My understanding is that CVS deals with that _very_ well. After importing
a vendor branch, you can checkout a version that has applied all of your
local changes on top of the vendor's changes - leaving only the
conflicting diffs to be fixed by hand.

As above, CVSup doesn't change the way CVS works - only how you get
the updates. What CVSup does (which it seems to do quite well, from 
my tests) is analyze the changes and efficiently send them, and make
good use of the bandwidth available, by balancing the analysis and the
updating processes.

Greg, could you give a clear description of the difficulties you
percieve the approach will cause?
