After some feedback about problems with building Kowari we've decided to release a new version that will compile and build successfully - this was due to problems with Barracuda. The upshot of this, though, is that all the bugs we fixed and the features we've been working on like Jena and JRDF support, RDQL, improvements in resource allocation and handling, and a Swing based iTQL UI get released.
We're also having fun loading millions of triples on an Opteron system running Linux. It gets about 4,000 triples/second after 13 million triples - which isn't quite fast enough, of course it's never fast enough.
