When all devlopment is performed on one platform and under one set of devleopment software, then you can start licensing, but why. There is enough regulation out there now to drive you crazy. Do we really want to have more? SOX is a great example. I don't know what the next flavor of the day will be, but I am sure it will cause more headaches. Regulation is one thing I hope never hits our world. It is doing enough damage elsewhere.
