rsync is horribly inefficient (not the protocol, which is genius, mind)
because a client coming by and asking for updates basically ends up
requiring the moral equivalent of
"find . -type f -print". Let me repeat that: each client. Not fun.
Why use rsync, then? Why not have checkpointed logs on cpan with
additions/removals logged by date so you can roll forward on the client,
processing only those files? It would be trivial to set up and a lot more
efficient.
We wait your implementation breathlessly. By the time all the CPAN
mirrors have started using that, we probably will be rather blue in
the face.
