I was recently contacted by Phil Barker, Santy Chumbe and Lisa Rogers of the ICBL in Edinburgh, Scotland.
Long story short, they are working on the The Bayesian Feed Filtering project, they will be using Sux0r for this project, and you should check it out. The full project proposal is available on the About page.
If things go as planned Sux0r will get a RESTful API out of this. Very exciting!
