There's an interesting post here about block propagation times:

https://bitcointalk.org/index.php?topic=88302.msg975343#msg975343

Looks like the regular network is reliably 0-60 seconds behind p2pool
in propagating new blocks.

So optimizing IO load (and after that, threading tx verification)
seems like an important win. Lukes preview functionality would also be
useful.
