How about virtual disks? This is concept a from RSX-land.  What you do
is create a file as a "virtual disk". You access this file through a
special device driver which looks at this file as though it were a
disk.  You then disable disk quotas on this virtual disk.

Glen Everhardt was working on a driver to do this, I'm not sure if he
ever got one running. Early versions had the problem that the file had
to be contiguous, and that you had to have the block id in order to
set things up.

Does anyone have a virtual disk driver around?
