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. >I thought there were standard models? I assume they all suck? 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?
