I never said that they weren't shipping. I said that it wasn't widely
available. If your box talks to a different vendor's box, then you have
a problem. This is what interopability is about.
So, unless you have such a box at BOTH ends, the end that can do both
still needs to support multiple SAs between end points so that it can support
having QOS and VPN done in different boxes.
