I came across the following link on google’s code pages: http://code.google.com/apis/analytics/docs/tracking/asyncTracking.html
It basically details the asynchronous loading of google analytics. I found this to be a very cool addition to an already powerful package that I rely on.
However, one thing that I haven’t been able to successfully figure out. What happens when you want to load in two instances or two different accounts? On one of my sites, I use my own google analytics account plus the clients. This tracks the traffic fine with the non-asynchronous method. You simply make a new instance of the ga object and assign a new ID to it. However, can I do the same thing with this asynch method? I’m kind of wary to try it because I don’t want to lose any data.
Anyone have any experience or have any links to where I can find this detail?

I found this link in the documentation: http://code.google.com/apis/analytics/docs/tracking/asyncUsageGuide.html#MultipleTrackers
I think it describes the multiple account setup you are looking for. Enjoy!
@Joel Clermont: Thanks Joel! Seems like I should have searched a bit harder
