possibly someone could, but not me ;)
Do we have a log of referring URLs or which projects are hosted on the servers that requests originate from? (Sorry if I've understood the structure of toolserver/wikimedia server farm incorrectly)
We could probably get 10,000 lines of the access log and do some basic analysis on it to work out what requests are being used for. Alternatively, just informally survey the people on each wiki familiar with the role of toolserver tools in their project.
