It seems to be the Email::* modules, is there anything else to it? A proof of concept webmail module would be really useful, or even just enough bits to build one without having to jump through dozens of hoops installing dozens of C libraries, and reconfiguring mail servers, as well as installing half of CPAN.
looking at perl.org - there doesn't seem to be much you can do to 'get involved' outside of joining the p5p and p6p mailing lists and adding modules to CPAN.. at least for free -- donating costs money.
It would be nice if there was a list of projects, like Maypole, The Email Project, or the now dead/dying/neglected P5ee project.
Would also be nice to link up with the Apache Foundation as they seem to be focussing on Java to the exclusion of all else when we could be partnering to provide a sane and compatible API accross languages for key things like web services, XML, etc as well as collaborating on things like RMI and Messaging between Java and perl in native formats.
I know I can only spare a few hours a month towards open source projects and I'd like to help, but its hard to see a way in - the perl lists are time-sinks, contributing requires money, and there isn't a place I can see where I can sign up to help either a specific project like the Perl Email Project or anything... I'd like to work on improving searching for search.cpan.org but as Acme points out its T0p Sekr1t for some reason and is too lame to be useful sometimes.
