I've decided to write here a bit about Zaphod, which is to become a collaborative text editor. The version currently at datenzoo.de is the old v1, which basically works but has major design flaws. The reworked v2 will go online soonish, to allow others to chime in with better frameworks, browser compatibility etc.
Also, I will pimp some modules here that are up for adoption / CPAN release, like most of the stuff at http://corion.net/perl-dev.
