I am keeping an open mind that once I start STS and/or another P90X round I may have to /need to eat a bit more frequently...
I think timing of nutrition, especially when doing an intense program, is perhaps more important than frequency, and post-workout is when the body is screaming to replace the used glycogen, so that it can go from catabolic ('break down') mode to anabolic ('build up') mode more quickly.
I'd start with a post-workout 'recovery' snack (something easy to digest, with about 4-to-1 carbs-to-protein: I've used a chocolate soy milk).
