Actually they did a release of the special editions a number of years back that had the original theatrical prints
IT's still available from some places such as http://www.amazon.com/Star-Wars-Episode-IV-Widescreen/dp/B000FQJAIW/ref=sr_1_1?ie=UTF8&s=dvd&qid=1281865521&sr=8-1
Zyxel do quite an easy to use one

Actually it appears to be Lambda switching/Optical Cross connects. Lucent sell similar gear and I think the tech was invented at Bell Labs back in the 90s.
Essentially you're switching the path to destination based on it's optical components rather than the encapsulated data - so you pick the destination node(s) by selecting the appropriate colour(s) on a tunable laser and blast the data out effectively switching the data at the optical level without decoding it to electrical signals.
It's very fast and very expensive so I'm not sure it really has a cost/benefit equation right now over using traditional kit with a passive DWDM solution for example.
