This is very cool stuff and I'm sorry to be a dick and immediately look
for problems, but could ULPRs be used to launch a sort of "flash flood"
where the attacker trickles out requests for an unavailable key until
the key's ULPR web fills the whole network, then releases the key,
flooding it through the network?
I realise the data wouldn't travel across every link because of the
offer/accept mechanism, but it would still visit every node once, which
is a decent multiplier for a DoS attack.
Cheers,
Michael
