Situations where a single transmitter and single receiver are the norm are almost never the case anymore (at least in the wireless domain). A favorite paper on the subject is: http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=1624625 Cooperative MIMO, Spread Spectrum, and Cognitive networks potentially allow EM jamming to be avoided and more easily predicted. Perhaps DARPA suspects that the channel is, in reality, a non-zero-sum game. That would overturn Shannon alright!

Tog's great.

Apple's HI Guidelines are really the distillation of [practical, achievable] best practices, as laid down by all the HCI greats that have ever worked there:

There's plenty of theory and pontification, but this is backed up by API's. If only Apple would consistently follow their own dog pee.
