I guess I need to sit down and write up my ideas for the new rating engine. They're an extension of the flow network ideas I implemented on Advogato, but different. The good news is that it should be pretty easy to implement - unlike trying to do distributed computations of the Advogato trust metric over very large graphs, as lkcl and I have been discussing.
I'm talking to a bunch of people who might be able to make a real implementation of my ideas. I really hope it happens, as it's both interesting research and also potentially very useful. There are two functions that the record industry does well: getting CD's distributed to the stores, and promoting the records so that people know what to buy. Distributed file sharing networks cover the first half of that job pretty well, but I believe there is a void to be filled for the second part.
Meanwhile, the ghostscript hacking goes pretty well. I have my very own memory device that does transparent pixel compositing. I still haven't hooked up the transparency parameters yet, but lpd has done almost all of the higher-level plumbing I need for that. The next few days portend fun and interesting hacking :)
