Allmost everybody has such requirements.

What about using Netapps (with snapmirrors or snapsync), then you'll 
get a rock stable storage system... and available on all machines in 
real-time :p

With maildir and nfs you'll can get a very stable system...

Using database (eg postgres) as storage system can be a good idea 
(mostly when you'd like to search something), but when it get corrupted 
or fragmented... then you'll have troubles....

This is my 0,02€ ... :)
