Since I've push a new stable release of WWW::OpenSearch, I was able to push some new modules that depended on it. In particular WebService::Lucene -- a perl client to the lucene-ws java servlet. We've been using the module in production for just under a year with great success.
I've also pushed a simple Catalyst model to CPAN as well. However, once I give DBIx::Class::Indexed + Indexer::* the ability to search, then that model will have very little practical usage for us.
