I would expect to have to evolve with the market, and I don't really see a future in litecoin for the same reason you mentioned. That being said, some might and I wouldn't mind running litecoin rigs if people wanted to pay for the equipment.
Still though, the advantage I have with power cost and location would make something like this viable right? Someday asics won't be impossible to come by, and people still won't want to deal with the heat output and power consumption.
I only live like 20 minutes from BFL, too

As is though, I'm still on track to pay for my 3gh/s rig with coins. I guessed the difficulty would start jumping 25% every two weeks when I started, but that didn't happen for quite a while. Still hasn't I guess!
