I suspect that this is simply not quite possible today, although it's
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
is a workable problem, but it has not been worked to this point.
