This depends somewhat on where the backup is going to run from. If
you run a backup client from within the VM then most of them should
work just fine (including Tahoe), but Tahoe is a particularly bad
choice if you want to backup your VM disk image from the host server;
it does not support block-level backup so every time you flip a bit
in the disk image the entire image needs to be uploaded again. If
you are hooked into the unpacking engine you can push and pull
individual segments to a storage grid, but if you are going to go
this far then as a practical matter you might also want to consider
hooking into a more battle-tested cluster filesystem for improved i/o.

Thanks!
From the links below, it appears that Tahoe is the most promising
at this time, though one still
has to maintain an AllMyData account.
It would be nice to include the comprehensive flexibility of VMue
with the P2P scalability of Tahoe.
Also Tahoe can score big time if they can support VMware and XEN
backup.
Best,
