You can neglect the time it takes to unpack and apply the deltas.
As soon as the filter gets hold of a delta, ctm_rmail takes over
and does the rest. I'm already doing this on the fly to update my
ports-cur and src-cur repository on our ftp server, and even though
the server is usually heavily loaded and the 9GB disks aren't the
fastest ones, it often takes less than a minute or two.

The idea does not sound bad. We're already serving as a (unoffical)
sup server (mostly for NetBSD), so setting up a cvsup server shouldn't
be to complicated. In case I can find an entirely statically linked
version of CVSup 15 that will work on BSDI 2.1 and 3.0, I would be
willing to do a little testing (I once fought against the M3 compiler
and do not want to do it again, especially on a machine that has no
ports collection).
But you shouldn't forget even with such a CVSup server I'm still relying
entirely on Richard's server. The moment _his_ server fails for any
reason _my_ server will be useless as well. The past incident made this
very clear.
