Thanks for the suggestions. I'm a little new to all this so I think I'll
just try to get something going first :)

The option of having the datastore in ram rather than the filesystem is
quite attractive as it liberates the ramdisk space for use by other
things that do require a filesystem. I'll look at that option once I
have something going though.
