Just to add one more thing to look at... try reading about Sxip (pronounced 'skip'). They were a sponsor of YAPC this year and gave a presentation about their services/protocol. Not too shabby.

Thanks! Our Perl Homesite Package should be coming out later this summer. FYI, the link on your posting to our site is wrong. It should be http://sxip.com.
