This is a great write-up. Off-topic, but I'm wondering what bottlenecks you encountered with the straight Erlang + Mnesia prototype?

Mnesia is by far the fastest (and easiest to use) thing we've ever tried. The only problem was that it was more expensive to keep data in memory and that pointer arithmetic is so damn fast. And (the most important thing) is the 2GB limit Dets has :/
