eavesdrop implemented some call swapping and three_way feature, maybe it's possible to borrow some code there?

I was one of the guys that wanted this type of feature implemented on the core instead of on the endpoint modules or endpoints itself and I have to say that once you understand the code you understand why it is not supposed to be there. I now advocate to completely remove the feature because it causes only headaches and make you look for a solution in the wrong place.
