Which places in content/ do you want to use this in? Is it going to be a lot of metrics or just a few? If just a few, can this be done in chrome/ (i.e. does it have access to the events/data)?

I'm currently working on the CL that uses this. I'll add you to the CL so you can have a look as soon as I updated it.
