Unfortunately you'll have to wait until the white paper for details. Philip Ross has spent a significant amount of time and effort these past 2.5 years researching and implementing various solutions. I unfortunately can't summarize the solution in any succinct way, and fortunately/unfortunately he stays away from outlets such as HN (better for actually getting work done).

However, I can promise you that as soon as he's done, I'll post it on HN and personally send you a message.
