I remember seeing something like this a while back, and it'd be incredibly useful for a project I'm working on. Essentially there was a list of mutex names, with a list of malware identifiers (e.g. W32/ZeusTroj) that are associated with each. Unfortunately I can't find it anywhere, and can't remember the name of the project.
Right now I'd settle for just the mutex names alone, but if anyone knows of any projects that include this data it'd be extremely useful!
