MySQL is probably best for these replication volumes. SuperMaster
replication relies on very good communications between master and slave at
all times, otherwise new zones on the master may be missed on the slaves.

Alternatively, 32+MB zones smell like in-addr.arpa zones with a million
entries. Quite a number of PowerDNS users have had great results with
running a dedicated 'pipe' backend that generates reverse mappings on the
fly.

This might save you quite some headaches.

Please let us know!
