This is indeed a great technology. The "push" analog to the original BitTorrent's "pull". But there's also potential for abuse (or greater freedom depending on how you look at it!). Say I create a sync folder containing a bunch of popular films and then widely distribute the read-only key. Thousands subscribe. Now I have access to what amounts to a botnet that will widely distribute whatever content I see fit to deposit, more or less untraceably because the P2P network is so huge, and I or my co-conspirators can insert or retrieve content from any part of it.
That sounds like a brilliant thing for free speech, but watch out, I'm not sure there's a guarantee of anonymity in crowds for people who have read-write access, they may be identifiable.
Still reading the analysis of the system. Have to read through the spec.
It would seem to me that read-only peers would have to have the ability to propagate writes across the network. Why would they have to identify the origin of the change if they obviously have cryptographically secure evidence that the change is valid?
