Rebol is a fascinating language, well worth a look if you are a language-geek.

Also, it's creator Carl Sassenrath wrote the Amiga Computer operating system kernel, the first preemptive multitasking system on a home computer.

I've always felt the potential of the language and community was a missed opportunity because of the refusal to open source it. Languages like rebol thrive when they are set free. It's a shame really.

I totally agree. I think that Carl is just a little old-school to fully open it. Walter Bright of 'D' had similar problems that limited the initial take-up of the language.

Its a shame really as I imagine many net hackers would love Rebol, especially those with a penchant for Lisp and lisp-a-likes.

"Red" (https://github.com/dockimbel/Red) is an oss effort in this direction (but very young). Same author as Cheyenne.

Not named after a Native American people. Won't scale as well.

Haha. I think Apache is the only popular webserver nowadays that actually still can't beat the C10k problem [1] without an extravagant amount of system resources. Process- and thread-based concurrency sucks for HTTP(S).

Event-driven is the way to go.

When Apache 2.4 is released, hopefully the event MPM will help with this.

Yeah, the evented MPM has always been the redheaded stepchild of the Apache family, which is unfortunate.
