Basically, when I rewrote the module there was no one maintaining it and I could never get in touch with the author. I revamped it for our use but couldn't get it into the core module, and I believe eventually chx took over maintenance of the module for his company's use. Last I tried, I couldn't get the module from there to work, but that was a while ago and I haven't had reason to try again since the version I produced works great and included some UI improvements that I don't think made it into the current version. I'll defer to anyone else's actual experience on this, though.
