I have two questions regarding this:

1) In the age of the smart phones, could one not develop an app to do this calculation for you? It might be tricky to film the wheel, but I'm sure that can be done stealthily somehow.

2) Would this work on online roulette games who claim to simulate the real-world physics of a roulette table?

You can. This is another sophisticated way to cheat. People are using their smartphones to count cards for them which will get them kicked out.
