I’ve worked with Josh Rabinowitz to put together a demo of his SWISHED server.
The demo is hosted here at peknet. You can read all about it here: http://swishewiki.org/index.php/SWISHED_Demo
Our idea for this demo was to illustrate how you might use SWISHED, SWISH::API::Remote and HTML::HiLiter. Those are all Perl projects, the first two written by Josh and the last written by me.
