Hello Nick,
 While an iSCSI SAN will not have any problem allowing multiple hosts to
connect to the same volume, what it doesn't do is protect you from the
resultant corruption.   Each host will believe it owns that volume
exclusively.  Writes from one host won't be seen by the other host.   They
will eventually overwrite blocks written by the other and corrupt the file
allocation table.  The solution is to use a global or clustering fllesystem
that will manage the cache and writes.  Filesystems like GFS, Polyserve,
IBRIX, Tivoli, etc...   GFS is open source, the others are commercial
filesystems that run many thousands of dollars.
