There seems to be something of a trend these days to fail to equip cheap consumer laptops with decent expansion capabilities: no ExpressCard slot, USB 2 (not 3), no eSATA port. However, HDMI ports are still fairly common on such machines (at least on mine). HDMI's max throughput is 10 Gbps, well above either USB3 (4800 Mbps) or eSATA (6000 Mbps). Is it (theoretically) possible to use an adapter (and, presumably, a custom driver) to make the HDMI port function as a USB3 or eSATA port, enabling such a machine to use newer external hard drives at full speed?
I would want to do this under Linux, but am equally interested in knowing whether it's possible under any O/S.
