LightPeak is the technology and it was developed by Intel. The technology is 20 Gbps (not 10) 1 direction. They rebranded it Thunderbolt when dropping the optical for Apple. It is compatible with DisplayPort, USB, SATA, possibly even Firewire. The idea is to replace them all with 1 interface. The technology is supposed to scale to 100 Gbps. At that speed, it could even be used for many purposes. It is great technology and would be nice it if was adopted, but the cost is prohibitive obviously.
