That's the Optical Society of America Uniform Color Space. You can find out more here. Cartesian distance in this space corresponds to perceptual difference, more or less.

Although the space presented is a bunch of discrete points, there exists formulae to relate the three coordinates (L,j,g) to CIE x,y,z. The corrected formulae are tucked away in this paper on page 18.

The space has the property that perceptual difference roughly corresponds to Cartesian distance between points for differences more than 20x just-noticable.
Their win32 client version 2.01 features a copyright 1996 stamp, which almost certainly means their version 1.x code predates the November 1996 filing date. The client featured VRML no less. They also offered corresponding MUD server mods for their Pueblo protocol.

Mind you, this means Macromedia now owns this IP, thanks to a chain of acquisitions. The (partial!) source code to the client and the server mods are available in a variant of public license.

Just unplug the box from everything, including the power. Short of physical intrusion, the box is now secure.
Anyone who'd done any software validation knows that validating a program is bug-free is hard and not guaranteed. Security is akin to a bug. Geez.
I've seen statistics that in the real world, programmers spend half their time maintaining code. I can still compile and play Unix programs written in the 80s and 90s on my current Linux installation (one gets used to the few porting issues that may arise), meanwhile even with the available source of a Windows app written in 95 (Chaco's Pueblo client) I can't even hope to get the thing to compile right since it seems to rely on some "system" files which have mutated greatly over time. (Anyone got a spare copy of VC++ 4? Hah.) Unix also has some great glueware (sh and perl for example) for knitting together disparate programs into a coherent whole. With a bit of programmer discipline one can achieve a fair amount of effective modularity and reuse.
The earliest reference I can find to a videotex system is 1977-78 so far. The BT patent appears to be an similar technology. Videotex was capable of two-way transmission and thus interaction with touchscreens. http://www.well.com/user/mmcadams/videotex.html
This site mentions an interactive vote via videotex called QUBE. http://www.high-techproductions.com/historyoftel evision.htm
A link dating QUBE to 1977. http://www.pioneerusa.com/timeln.html
How close was videotex to the BT patent implementation?
It's clear that the message here is targeted at a US population. I've seen news reports elsewhere which mention that it's not uncommon for such DoS attacks to involve compromised servers (unbeknownst to the legitimate operators of the site) outside the target country, and I'm sure the FBI is aware of this.
Someone at the FBI is a smart cookie in responding decisively and publicly. I think it's a move to start up a division within the FBI that is dedicated to cybercrime and expand from there. This DoS attack might be ammunition in a future argument in favor of key escrow or somesuch. I noted that Patrick Naughton was nabbed in an FBI sting operation. Don't be surprised if the FBI continues to maintain a high profile when it comes to staking out law enforcement turf on cybercrime.

Hey, a new fan! :) Geez, lighten up. My site's just a vanity page.
Next I'll be hearing, "Shut up, Wesley!"
