[Gllug] Is there any demand for rsync based offsite backup?

What about a system were I would get X amount of distributed
storage/bandwidth backup capacity in return for donating X*Y amount of
disk/storage.  You only need a couple of people to get that started,
and it scales up quite nicely.

Once it reaches sufficient size you allow whomever it centrally
coordinating this scheme to re-sell the excess capacity.  Which pays
their bills, and those with servers can get free, distributed backups.

To some degree this offsets the always on computer cost by, in theory,
getting improved utilisation from the computers that are already on
anyway.
