Yes, it does some serious magic to uncompress on the fly while chatting
with a stock rsync at the other end. Craig must be an insane
programming genius to have tackled a project like that in perl and
succeeded.

If they are doing things where versioning makes sense, you should
provide a CVS or subversion repository and arrange things so the only
way any work is considered 'done' is when it is committed. If it is
more like spreadsheets and documents, something like 'unison' might work
with a server location holding the matching copy. Unison is like a
bi-directional rsync that keeps track of where the latest changes were
done.

The generic way is with the command line BackuPC_tarCreate which you can
find in the documentation. You can pipe its output directly into a tar
-x where you want it.
