Google Analytics for WordPress MU - Sitewide AND single blog solution!
It's great to offer your users Google Analytics, but it's even greater to be able to offer it to individual bloggers AND at the same time be able to capture sitewide stats for yourself!
Everybody loves Google Analytics. So a great feature of your WordPress MU platform is to allow individual bloggers to be able to simply insert their own Analytics code so they can track their blogs performance.
However, there's one big downside to this :( Usually it means that you can only allow your users to track their own stats, while flying blind yourself. Booo!
Well, not any more... this neat plugin allows you to simply enter your 'UA' code into a new field in Site Admin > Options AS WELL AS allowing your users to enter their code in Settings > Google Analytics.
And, they will both work together! Oh frabjous day etc. :)
And if that's not enough to make you go 'Callooh! Callay!' - well, we've also integrated this into our 'Supporter' framework - so you can restrict access to the individual stats to to paying users only (if you wish). Just visit Site Admin > Supporter once it's installed to set it to free / paid.

NB: To track all your subdomains separately you'll need to configure analytics and add in an extra line of code to the tracking code as described here (very easy to do): http://www.google.com/support/googleanalytics/bin/answer.py?hl=en&answer=55524
