Hate to rain on your parade, but this isn't really revolutionary at all.http://en.wikipedia.org/wiki/C10k_problem
Lighttpd is over 8 years old, and was able to break the 10k barrier when it was originally written due to the event-driven nature of the server. Note: 10,000 concurrent requests means less than 500k memory per request on a 32-bit computer with 4 GB of RAM, so accomplishing this on standard computers 8 years ago was quite the feat.
There are plenty of relatively mainstream servers that take this approach. Lighttpd is still popular, as are Ngix and Cherokee. I personally use Cherokee for my VPS, but thats cause its user interface looks pretty awesome. Using Cherokee + Postgres + PHP only uses ~200 MB of ram under stress ("Stress" is ab -c 100 -n1000 on the blog's homepage), although I'm not running much on my server yet.
And still, Apache has its place as the 800lb Gorilla of the Web World. Every web package seems to target Apache still (Lets see, phpbb, wordpress, and so forth have .htaccess files, which is an Apache-specific feature).
First Strike +1/+1 and Indestructible.
