My lab was dynamips 3745s with 12.4(15)T14 (that's the exact version that was on the real lab last time I went). Worked like a charm over here. FWIW, I would make sure not to have those neighbors activated under the IPv4 address family unless told to do so. And as I said before, you don't need the VRF CE neighbor defined under the "main" BGP at all, you just put him under "addr ipv4 vrf B". That would minimize chance for feature conflict in the real lab, but in this particular case it does seem to work anyway.

It really does not make sense that it would not work. Everything loos right to me. Thanks for the look. I am going to try and re arrange some of my real equipment and try this again. Tell Jason I said yo. I need to get some sleep been a long week.
