But it's more targeted for the explicit need of netbooting and remote management. But in a sense, for VAXen, it would be great if we had the possibility of getting all the netbooting though MOP and not need DHCP and TFTP. Not sure if that is possible, though.

Can MOP supply the IP address to the system?  If not, you're not going to be eliminating DHCP (or BOOTP).

Yah, my baseline assumption would be "SIMH can MOP boot on whatever real hardware could because you run the firmware ROM".
