I’ve give credit to Tara for provoking this one.
i use this, one of my favorite Mac OS X software sites, has enabled OpenID consumption using miyagawa’s OpenID plugin for Catalyst.
Note: I hadn’t realized, but despite its Rails-like trappings, i use this is actually a Perl app powered by Catalyst. One issue that was revealed in using the Catalyst library concerned Yadis discovery of delegated OpenIDs. Until I hear from Marcus, you’ll either need to use your direct OpenID URLs or the traditional meta-tag method of delegation until support for Yadis is baked into the library.
