I believe so. I'm just guessing at CVS's behavior, but I *know* that
CVSup only sends compressed diffs of the changes to update a cvs
repository or a checked-out tree. afaik CVS sends the entire file,
compressing it for transmission much as does CVSup.

Not entirely, unless you can guarantee uptime on Internet routing. I
see outages on occasion which I don't think are local to hub.org.
That's no news to anyone, but it does seem relevant when discussing
the merits of local vs remote repositories.
