If he is intent on Raid 5 and lvm, then he may be contemplating using the 
LVM for the parity. This would reduce the number of hard disks lost to 
parity wouldn't it?
For example, 12 disks on 3 machines.

1) Each seperate machine has 4 disks, raid 5, and then stiped = 3 disks lost 
to parity
2) If LVM were to be done across the network, (in theory) only 1 disk lost 
to parity.

Obviously, if you could afford 12 disks, it would be a lot more sensible to 
go for a fibre attached raid or proper NAS

Yes, but why?  LVM is notoriously sensitive if a drive were to
"disappear" such as a network problem would give, etc. The SVN version
