Setting up Google Analytics + in a multisite network


I would like to know how GA+ is intended to be set up on a multi-site network. I'm wondering if there's a way to avoid making each of my users set up their own Google Analytics account. For example, it would be great if it could work like this:
1) Set it up once for the entire network using my own parent GA account.
2) Make it so any traffic from any site in my multi-site network (or their mapped domains) gets logged to my GA account.
3) When presenting GA stats for each site in my network, make it so that user can only see a filtered view which only includes their subsite and any of their mapped domains.

Is this, by any chance, how it's designed to work? Please? :slight_smile:

If not, is there any way to do this that doesn't require making my users sign up for their own Google Analytics accounts?
