I don't know that anyone is currently working on the new transport code.
It still needs some work to define all the various protocol/transport bits
(see cam_ccb.h), and implement it in all the SIM drivers.

Keep in mind that we'll restrict things according to the *path* inquiry
(where the transport code puts things), not SCSI inquiry.
