some thoughts about venti that go around in my mind:
1. how stable is the keying ? sha-1 has only 160 bits, while
data blocks may be up to 56k long. so, the mapping is only
unique into one direction (not one-to-one). how can we be
*really sure*, that - even on very large storages (TB or
even PB) - data to each key is alway (one-to-one) unique ?

Not that this analysis is without flaws, though.
