No, data are not copied into RAM, like this do REALbasic.

I believe this exactly happens in background of binding.

Looks to be :)

In fact idea of binding is very simple. This is a contract.
Contract between our classes (V4CC in this case) and Cocoa.
In this contract we promise name special functions in special way.
So Cocoa can self find them and call.
