They run on top of the wow subsystem which takes care of converting the api 32 calls to api 64 calls. Nothing more, nothing less. So the impact on performance is very mild, its nothing like running the application on a virtual machine or having it emulated....
Read my post again. You are somewhat wrong. There must be a 'sandbox' because most 32-bit apps must be protected from additional memory available to the system or they will crash. Read up on it.
