There hasn't been any prepared releases yet, though checking out the project directly into eclipse works. The API is designed for ease of use - it is supposed to make a programmer's life easier, not harder. The API documentation is rather extensive (by my standards, mind you), albeit not complete.
The code was originally leveraged from the more refined parts of my previous app (BOINC Echo - sf project page), though it hasn't yet been tested in other projects or faced the scrutiny of fellow developers. I'd be delighted over whatever feedback I can get. I'm hoping this would help me in identifying some bugs and/or needed features that escaped my sensibilities.
