Also, if nobody has written one or is working on one, I am considering writing
a script to provide basic cvsup like features/functionality for repository
updates via rsync.
I'm not sure what you mean with that.  Isn't calling rsync enough?  Maybe 
people could be interested in my script to download + update various 
repos.  See attached.  Maybe you can figure out the file formats yourself :)
