Well, I concentrated on the CAM side of interface. The underlying
hardware is one of device-dependent parts. 

BTW, I looked up the list of of absolutely neccessary calls
for simulated SCSI:
XPT_SCSI_IO
XPT_RESET_BUS (at least silently return success)
XPT_ABORT (at least return CAM_UA_ABORT)
XPT_CALC_GEOMETRY
XPT_PATH_INQ
