I'd agree with removing the provisioning tool from the main tahoe
executable, you may as well move the reliability calculator into its
own small program as well. I wonder how many users really use those
two programs unless you are in the process of setting up, tuning or
upgrading a tahoe grid with additional (or less) nodes.

cool, I was also wondering if the MTBF needs some updating as well,
the current value seems to be based of an old google publication which
I couldn't find (if anyone can share it, it would be great). I think
having a few 'standard' MTBF's that manufacturers appear to be selling
drives at might be worth putting in as user selectable values as well.
BTW I'm finding the provisioning tool to be fairly useful outside of
tahoe for estimating sizes and costs for a storage system :P


Thanks,
Jimmy.
