Not a problem if you have always-on Internet access, which not everyone
does. I consider having to periodically update a guessable key to be not
totally acceptable for a number of reasons. Not only do you have to have
regular Internet access, but it also provides a way to track a
publisher. If you're inserting updates from the same node it might be
possible to incrementally track you down one hop at a time. This attack
only requires the ability to snoop one connection at a time, not total
surveillance over the whole network. Key hashing doesn't help since
the next key to be inserted is known. Connection encryption doesn't help
since a MITM attack can be done on each connection between nodes. PKI
helps somewhat, but irregular updates help a lot.
