How about if you start a page with a list of the 9p file servers you know of, say on the plan9 wiki, and then email 9fans asking them to add any that you have missed?
I can see how such a thing might be a useful resource to people on the list as well as a promotional tool. It could also (perhaps) focus attention of those with time and interest towards the best ones to tackle next. "best" in this context is of course a moveable feast. just my 2cents worth -Steve
