Switch virtualization in FOS 6.2.x

So, has anyone else played with the new switch virtualization features in FOS 6.2 yet? I got a chance to work with it a bit on a new 5300 we brought in (before we put it in production). I'm curious if anyone has actually implemented it yet in production.

While I'm at it, I'm a bit curious about how ControlCenter might discover the virtual switches on a physical chassis. If anyone has done this yet I would love to hear more detail. I haven't had a chance yet to dig into it too far and I don't have a switch I can test with. We usually only have a day or two after we receive them before we have to get them on the floor.
