The compression and decompression happens within the client/server
- there is no tar or unzip or whatever extra process involved.
Also, how would tcpdump "show decompression activity"?
Of course it just shows the ssh packets.

I believe the mirrors allow whatever compression you ask for.

Per person? Why don't you just sync to one place,
and let the local users sync from that? That alone
will cut your traffic by a factor of 1/persons.
Also, how "many MB per month" is it actually,
and what percentage of your monthly traffic is it?
I wouldn't be surprised that
(1) you are actually using the cvs -z compression already
(2) the savings of compressing some more are negligible
in your overal monthly traffic
(3) using ssh compression makes the inner cvs compression irrelevant
(and someone has numbers to back that up)
