I've seen the many ways to do shadows like shadow maps, stencil buffer, glsl, zfail, etc. I want to know what's the fastest way to do shadows for real time rendering. If I have a moving light in a scene with an animated mesh what's the best way to attack this? I don't want to do multiple passes, is there not a single pass shadow effect?

For a single pass none that I know of. A scene with a lot of polygons you would be better off with shadowmaps of some sorts...

Shadow maps are faster than shadow volumes? I thought Carmack's depth fail shadow volumes was one of the best? Where is the best place to find some good resources on OpenGL shadowing?
