[mythtv] Multi-stage video storage

Just a quick thought/question I had.
I think it would be very handy to have a multiple level
(2 at least) video location database.  Take this as
an example:

The main mythtv machine has an average amount (~36GB) of
very fast harddrives that can take serveral recording/playing jobs
at a time.  But the final capacity is rather limited.  A
second machine on my lan has perhaps another 100GB of slower
disk space.  I don't want to do all the recording over NFS to
the 100GB, but if myth could record to the local drives, then
spawn another process when its done (and perhaps idle) to move
the files via nfs to the remote machine.

On playback, it could either play directly via NFS, or probably
more efficently reverse the process and copy the file back
(if space is available) so it can play locally.

This keeps the fast drives available and clean, but yet
gives the added space of the second machines larger capacity
but slower network and cpu resources.

If I was to dream, this could all be handled by the OS filesystem
transparently to the application; but I don't know of any
such features in standard or addon filesystems.

I might be willing to take this on as a project myself...
