In fact the idea of publishing a subset or censored view of EventLogging logs is something we’ve been tinkering with for a while (I think Erik M brought it up on this list a while ago).

Replicating a subset of the logs stored on s1.log on labs db sounds like the best way to approach the problem. The added bonus is that by having this (public / censored) data exposed via labs db, wikimetrics would be able to access it out of the box.
