Online card counting

[fluff]

I know a few sites that do this, most famous is probably the Golden Palace group. All of these have pretty crappy rules, and very light penetration (less than 50% on an 8 deck shoe). Plus they are very very slow because the dealer has to slide each card over the reader and wait for it to display on the computer.

While you could technically find occasional +EV situations, I think you'd make more collecting cans.
