I've been pretty busy at work these days, so I have to admit 
that I wasn't able to follow the whole VCS discussion from 
the very beginning.

I've to agree which Matthew. 
Implementing IAtomicBrowsableVersionControl does not 
really make much sens for CVS. Unlike in SVN a revision 
is not unique, so you can't find any changes with only 
a revision. You always need a file and a revision. If I 
understand correctly, repositoryRevision() is nothing else 
than calling "cvs status" on the given file. It will give 
the repository revision, which will (if the file's up-to-date) 
be the same as the lokal revision.


"cvs history" is a very strange command. I never used it, 
because I could find no real benefit from it.
What I know about this command is this: It gives you any
changes that have been made on the cvs server. Not only 
for your checked out directory or file, but for any file 
that is stored anywhere on the server. There 
are a lot of options to limit and filter the output, but 
you still always get output for changes which were not made
in the directory you've checked out. 


Greets, Robert
