Or how about simply transmitting all revisions and certs, and omitting 
only file contents?  It seems like this should reduce the network 
traffic by a considerable amount while being much less complicated than 
approaches that omit revision data.

Currently, an initial pull from venge.net restricted to 'net.venge*' 
transfers around 71MB according to mtn's tickers.  The following simple 
estimates suggest that pulling only revisions and certs should transfer 
around 10MB:

$ mtn automate graph |cut -d\  -f 1 |xargs -n 1 mtn automate 
get_revision |gzip >nvm-revisions.gz
$ mtn automate graph |cut -d\  -f 1 |xargs -n 1 mtn ls certs |gzip 
>nvm-certs.gz
$ du -h nvm*
1.0M    nvm-certs.gz
9.2M    nvm-revisions.gz

Perhaps this would be good enough?

Christian.
