Take a look at FireWire interface chips. They have hardware specs close or exceeding to what you are looking for. Current chips will do 10MBps ether easy. Unfortunately I have never seen any of these 'off the shelf'. It is just barely possible that a IEEE1393 ASIC or FPGA can be programmed to do 10MBPS ether. I have never tried to look at this, but it's an idea. The technologoes are close enough speed-wise.
