We have made the Live Tracker opensource into a service and have launched it on http://www.live-tracker.com This service has the same features as open source.
Live Tracker 0.5 beta version will be released today.
zip and tar balls will be uploaded as a part of this process. Sorry people, no documentation yet. There is absolutely zero documentation for this version, as of now. Will be adding documentation during the course of this month. In the mean time I would encourage people to start using the binary version - .war and start experimenting.
