I think the new mega site would be more ideal for that...
I was thinking of a nightly build or collaborative film editing sort of exchange where ongoing change proposals to some files within a large set of files could be made to update in a syncing sort of way: rehash the 800GB collection and bittorrent would update only those that have been altered since last hash-check. In a globally distributed group it could hugely reduce data transfers.
Not an ideal way to go about it but for low cash and/or low bandwidth groups it would be a good workaround. Using conventional hosting (eg: mega) means re-downloading everything by everybody every time.
