The first release of Pod::Webserver is entering CPAN! It's like perldoc crossed with a tiny httpd (done with LWP's HTTP::Daemon). So if you're going to be reading a bunch of docs, you run "podwebserver" and it starts the daemon, by default on port 8020 (ar ar ar 80/20 Rule), and you point your browser at http://whatever:8020/ to browse the pod.
Of course, it uses the new Pod::Simple to do all the real Pod conversion work, and LWP to do all the HTTP work. That's why it's only a few hundred lines. So obviously it doesn't require Apache to be installed or anything.
