Kowari 1.0.2 is now released - much better than the last one. Even available in a bite sized 14MB version. Unfortunately, we didn't get the anonymous node bug in our Jena implementation fixed in time. The next release should be within the next 2-4 weeks depending on the progress of the currently outstanding bugs.
BTW, you can now do things like: "select $s $p $o from <http://www.w3c.org/2000/08/w3c-synd/home.rss> where $s $p $o ;". You can combine local and remote (via file or http) models by using "and" and "or" in the FROM clause.
