Is there any way to tell CRUST to leave the wifi alone?

I don't think that's possible with Crust. It's a whole separate chip on the board that handles stopping the CPU and most other components when it takes over. The hardware clock is basically all that keeps running, other than the Crust chip itself.

I think a possible solution might be to have a "sleep" option that just shuts the screen off, and then maybe scales the CPU frequency way down.
