Lambda the Ultimate

From reading the patent, it looks like the idea is similar to continuation based web servers, but requires manually CPSing the code. It doesn't mention call/cc or any other continuation operators.

now it's just 6,205,469 to overview before touching any open-source code! perhaps the patent systems could get a hint from something like WS-Discovery?...

At the end of 1998, I published some web pages on the topic of applying the idea of continuations to web site design and implementation. The term I coined to refer to some abstract concept involved was "hypoknot', and this terms is sufficiently novel that you can search in some internet web archive time machines and expect to hit nothing else besides what I wrote, probably.

This stuff might or might not invalidate the patent. But it will certainly undermine any claims about the use of continuations with web site architecture, especially if the idea is the use URLs embedded as pages as a way of serializing the representation of continuations.

Here's an excerpt from one of the pages I wrote in November 1998 (in a page titled "IronDoc Hypoknot Page" or something like that). I can post more stuff if folks end up being interested.

(quote)continuation · The hypoknot idea is also similar to the notion of a continuation in systems that are able to represent the resumable flow of control in an execution thread as a first class object. In this sense a hypoknot is an explicit representation of delayed computation, when dereferencing a hypoknot has the effect of completing additional steps of some incremental computation. Presumably the result of many such incremental computations can include new hypoknots that represent the ability to conduct still more steps in the computation. Note this model corresponds extremely well with commonplace design patterns used with http-based hypertext system on the web, which tend to return web pages with embedded links that permit navigation to alternative computational continuations.
