in reply to Best RSS modules and techniques?
Not answering your question directly, but: I'm the (sorta new) maintainer of XML::RSS and I'd be happy to get some help improving the module. It needs a documentation update because it does support 2.0 pretty well. It needs Atom support, too.
If you're willing to pitch in (at least testing it), I'd be happy to send you pre-release tarballs of the new version.
