Are There Any JXTA Users Out There?

Whatsmynickname passes along this query: "I wasn't aware of the JXTA protocol for P2P, but I've recently been tasked to look into it. Has anyone done any serious work with JXTA yet? Is this protocol going anywhere yet? Yeah, I've searched Slashdot, but past articles, did not leave me with a warm-and-fuzzy feeling that big things are happening with JXTA. Looking at the C version of JXTA, nothing much has gone on there, judging by the last time source code has been updated. When you consider it only supports a http transport, the C version looks like it needs work. The java side has a demo program that I've played around with and looked at via a network sniffer. So far, I've had some reservations about using XML as it's message framework, and the model used for peer discovery (a peer sends a discovery msg with some or all other peers replying). Comments?" For those of you who have tried JXTA and were let down, what drove you away. For those of you still using JXTA, what keeps you using it as opposed to other P2P frameworks?
