I suspect that this is simply not quite possible today, although it's close. The BEHAVE IETF working group is the place to look for the latest information on this area. I have tried a couple of solutions. The one that worked best was IVI, developed in China. It generally worked well and was fairly fast. It's big problem is embedded IPv4 addresses in things like JavaScript. This is a workable problem, but it has not been worked to this point. -- R.
