I'll be impressed if your solution can operate with less than 100% degradation under a situation where all global (and regional) internet infrastructure providers are highly incentivized to attack it to oblivion and do so with vigor. A related assumption is that the U.S. NSA or a like replacement 'owns the net' and their analytical abilities of traffic down to the individual packet level are very high.
Your (or A) solution does not need to perform in such an extreme environment indefinitely but it must have a realistic potential to hold out for a period of years.
These threats are not at all far fetched to my way of thinking. A solution which cannot deal with them is simply not very interesting of valuable to me. If we don't see such an environment it means that mainstream solutions continue to work more or less as they do now, and to me they work just fine. I'm interested in how to deal with a world in which they do not.
If you assume that, then just stop now and shoot yourself. Game over. We will sink into a Dark Age and everything will be expropriated.
I assume mankind wants to fight when given the tools to do so.
The system the bastards rely on doesn't run without the knowledge capitalists. We run their system.
If even a few % of us start working on an ecosystem of solutions, they are toast.
They must obscure any takedown as DDoS or hackers, because if they simply filter data on the internet backbones, this will be a clear signal to the hackers that we've entered a war of totalitarianism. If they overtly declare war on hackerdom, they will lose and they know it.
So instead it will be proxy battle.
