Also, before you decide anything, I should let you know that I decided
to go ahead and write a general purpose rsync based mirroring tool, both
for keeping our own dcvs copy updated and for doing convenient rsync vs
cvsup benchmark testing.

I have been working on it for two nights now.  It is written in Perl
and, so far is working pretty nice.  I call it *mirror*.  I have
a configuration file for it that is pre-configured for all the DragonFly
rsync repository mirroring sites that I know of so far.  It is even more
convenient than cvsup.

I plan to make it available, hopefully in the next day or two.  I was
going to set it up as a standard installable source package 
(i.e. make install) and write a manual first.  I was considering hosting
it as a project on my own site or one of the project hosting sites or
see if you guys are interested in putting it up on the DragonFly site.
I would be interested in feedback.  

It has some pretty nice features so far.  Just to give you a little
preview, I have included just the configuration file below for DragonFly
dcvs mirroring.
