Sure, but I think Tom's question is how do you get from the plugin to wherever
you want this data to be? There's not much you can do with the data at that
point. You would end up having to reconstruct the entire stats collector
infrastructure to ship the data you want out via some communication channel
and then aggregate it somewhere else.

Perhaps your plugin entry point is most useful *alongside* my stats-domain
idea. If you wanted to you could write a plugin which set the stats domain
based on whatever criteria you want whether that's time-of-day, userid, load
on the system, etc.
