Reading the name I was hoping you were going in the direction I'm
thinking of going :)
That is, pushing statistics to statsd [1] and from there to Graphite.

My rationale is that we are going to use statsd for other components
of our architecture; but even looking at just Varnish, it has
potential to be more scalable. In particular, I'm looking at
collecting more in-depth stats via the SHM.
Last year I did a spike on that [2,3] and while my naive approach
broke down under moderate load, it looks like if I keep processing at
a minimum and just fire off UDP I should be able to keep up with a
much higher traffic.

I'm not ready to work on that right now, but I will get there. If this
is something that might interest you, maybe we can combine efforts.
