Ok, I though trying to write RRDs via NFS with like 200ms+ connections would be an even more terrible idea :p RRDs are fairly effective to compress, you could have rsync gzip them during transfer :)

Centralised mysql and rrd via NFS would be easier and lower bandwidth. Observium was originally built with this possibility in mind, though we rarely push it.
Syncing rrds is a terrible idea, look at the size of your rrd folder :)

Well I guess the hard part would be to have a distributed database? I have no experience in DB-clusters but if you could have a MySQL-server in each region that syncs with each other active/active-style (no idea if that is possible considering the delay) then it should not be to hard to just have a rsync-job syncing the RRD-folders(does not need to sync every 5min, the data will still be there) and modify the poller-wrapper to instead of launching poller.php instances locally make it launch them on remote servers.
maybe. /Markus
