BSD SCSI-CAM porting to QNX

To cover the people who are not subscribed to .porting

Since we lack the SCSI-CAM subsystem to develop a generic SCSI driver in
QNX, I am thinking of porting BSD-CAM to QNX RTP, yea I know it is a big
task, but I am not sure how much feasible it is. Currently I am going
through the BSD CAM architecture.

I just wanted to check already any of the developers involved in such a
task(Apart from QNX developers).

I will appreicate,If they can share their experiences,things to be
cosidered,sources of information to be studied, any sort of info which I can
make use.

All of Your inputs are valuable.

Thanks in Advance
