Sorry, I don't understand - what would the index contain if you were doing
random replacement?

I guess the question is what we're trying to protect against by rekeying.
If it's an attacker pushing a single block out of our cache by inserting
other blocks and then requesting the target block with HTL=1 to see whether
it was pushed out, I don't think we should spend any effort trying to
prevent the attack. There are a hundred worse things an attacker could do
with a similar amount of effort.

There are standard models for things like phone and web traffic, but the
question is how will people use Freenet - how much of the traffic will be
file sharing, messaging, web browsing, etc?
