LastGraph is still undergoing rewriting after the beta showed up some lovely bugs (including inverted labels and labels everywhere they shouldn't be). I'm working on it over the weekend, after my week was overtaken by the sheer mass of activity involved with university and Fresher's Week (I find it strangely ironic that it's actually more timeconsuming this year, when I'm not a fresher).
I'll give a progress report soon; hopefully I can clear up the fetching errors (Last.fm have also kindly agreed to let me access the API more often, so fetching speed should increase), and make uploading to S3 faster (aegis' upload speed is somewhat limited, so it will be done directly from the render nodes themselves - this does somewhat scupper my plans for distributing the rendernode client, though, as they need my S3 secret key to do this, unless they can upload elsewhere and pass back an appropriate URL).
