Try some ram disk? If you got gigabit ethernet - maybe setup RAM disk in =
Linux (quite easy but don't know how right now ;)) and share it through s=
amba.

Maybe it'd be goot to create some "README.ms-cluster" file and add it to =
every release.

I'll be placing soon (1-2 weeks) one iSCSI system to the Internet for my =
customers to test compatibility  (I've web interface for it) - so I'll se=
nd access informations to this mailing list.
