Considering ressurecting pTunes as a searching for the campus iTunes Rendezvous sharing community (number of people sharing seems to have doubled since I last checked).
Sounds easy enough, given the existence of OpenDAAP, right? Well, I can't seem to get any of the Perl based tools to work (dapple and a stand-alone script that I found). The Java tools aren't having much luck either.
Hacker interest seems to have dropped since the initial iTunes 4 release in April. I've seen a few references to 4.0.1 requiring a bumped version number, and the necessity of keeping the HTTP/1.1 connection alive (LWP seems to be ignoring my request for this), but then others claim that existing tools should just work as is with 4.1.
