Ok, so that implies that it is burned into hardware and as it is ASIC-based hardware and not FPGA, they can't reprogram the hardware with a code update (one of the advantages of FPGA-based hardware). > Cisco is just one example.

Ask your account rep, then report back with facts. > Arm-chair engineering accounts for too many emails on this list. The usage I have in mind would be transparent to the end stations and, frankly, someone who produces provider gear and CPE that can take advantage of that space is going to have a great selling point. There is some gold under there for someone. 240/4 is a great big "dig here" sign if they want some of it.
