[9fans] Venti and the hash / public key in plan9

Hi... I've been reading the papers about Venti. There is an
explanation about the low probability of the repetition of a hash
string in a normal-sized nowadays hard disk. Anyway I've don't
understood what does Venti do when a hash is found in the stored
blocks, and the contents of the blocks are different (the
low-probability case). I imagine there is some code which does not
give a data-loss... Can someone give a small explanation about that?

And also about public key management in plan9 for (at least) 9p
connections. I've seen in the paper regarding Security that there's
used only Shared-key authentication (p9sk1). Maybe there's something
new in the actual distribution of plan9.

I'd like there to be dates in the plan9 papers... :)

Thanks! (I'm quite new in using plan9/inferno)
