In the end, this might not be exactly HA because you'll have a period of time that isn't covered and may stretch for quite a while.

An interesting idea: use drdb to create an HA pair for the read/write ZEO service, and also use a read-only ZRS secondary. That way when the primary r/w ZEO server went down, read transactions could still complete until the second r/w ZEO server could start.
