I believe the MAC address of every frame on the subnet has to be examined. Overhead is quite large. It's a lot of data to cache, with most of it being junk. A better approach may be to use a switch and have one port dedicated to the 64, with the 64 being the only device on that port. The switch can help weed out a lot of the junk frames that would need to be thrown away anyhow. Combine this approach with a buffer for the frames containing data actually intended for the 64 and maybe some other folks have some good ideas??
