I'd also *love* to see a phone with two SIM slots - I can see the 
interface now, when you dial a number, it prompts you "with dial as: 
<number 1> <number 2>". I also like the Idea of having certain contacts 
set to automatically dial using a specified sim.

There are a couple of interesting possibilities for the openmoko to be 
able to do something like this using only one sim slot:
