If you are thinking of connecting two computers together via eSATA, don't! SATA/eSATA is not a network connection. It is for hard drives. Tie two computers together this way, and you stand a good chance of frying the SATA controllers on one or both motherboards.
I dont know waht eSATA is, but I mean the SATA cable with the smaller jack.
eSATA is simply a SATA connector that is external - on the back of the computer. Regardless, my answer is the same. If you connect a SATA connector on one motherboard to a SATA connector on another motherboard, the best that can happen is nothing. The worst that can happen is that you'll fry the SATA controllers on both boards. SATA controllers expect to see a storage device on the end of the cable. If a controller were to see another motherboard, it would have no idea what to do with it. The SATA interface is for transferring data to and from a storage device. It is not for networking.
