For what it's worth -- unless we already have a scheme for producing bibtex -- here's my bibliographies and annotations (basically [1]) on 7 of the papers. Unfortunately, many of the papers are still not present; also, anyone know when the streams will be up? [2] still says "None available as of yet. Check back after the first day of the WikiMania program.".
