Actually... On the 2600, you need to be able to respond instantly to
controller input.  Not all games simply check it once per 50/60 Hz frame,
with the obvious exception being anything that reads the paddles.  Have
a paddle read miss by even one scanline (0.0063 milliseconds), and the
onscreen paddle missed the ball on one machine and not the other, and
there goes any hope of synched emulation.

I don't think peer-to-peer emulation is even possible.  Client-server
certainly is, which must be what Nesticle and all the other emulators
capable of it are doing.
