Any mining gurus want to speculate with me on what IntelliHash will be?  I'm guessing something like variable difficulty - something that increases the nonce search space and cuts down on chatty communication.  Or maybe just 48 bit nonces.

If it is a fatter nonce/bigger search space will this up stale rates?  Do you build some kind of interrupt so you can restart on the new share right away or do you just let the other hashers finish and give them the new share when they're done?  I know jack shit about the tradeoffs here and this EE stuff.
