I'm working on it over the next two weeks.  On the host and firmware
sides, still left to do is an extensible control protocol for the VRT
devices.  On the host we still need to parse all the IF-context packets
similar to how the IF-data packets are handled.

Using a non-USRP2 prototype, we're sending good IF-Data packets at
120MB/s (30 MS/s 16-bit I & Q) and are expecting to be sending all the
relevant IF-Context packets in the next week or so.

As to when this will be back ported to the USRP2, I can't currently say.
