Yeah, I stayed up just so I can reconfigure and get back to shoving.
Hope to see some more shiny blocks after work tomorrow.
One thing that sucks about N-factor changes is that the actual difficulty adjustment only takes place later (e.g in 615 blocks from now).. which means that the next 615 blocks will take 64 seconds to find - and not 32 as intended. Meh.
A good coin design could automatically downscale the difficulty at each N-factor change.
Also there is no good reason why the scrypt N parameter always has to grow in powers of 2 (apart from the tiny detail that in the code you can occasionally write &(N-1) instead of %N which is a tiny bit faster.
