Google is just default 2, just like NAS said, in my book! Where is their DC forum at?
With that said, I've been checking a few things about Google with 1 of the machines I have folding for Icrontic. It seems like it is very easy to change the team number in the registry from google's(446) to the team of your fancy.

This is where the userid and username was installed in the registry on this box , running Win2K: HKEY_USERS\S-1-5-21-842925246-1935655697-1343024091-1000\Software\Google\DcClient . In there, all you have to do is to change the TeamNum key from 446 to whatever you want and it will start folding for the new team designation, as well as in the client.cfg file under c:\program files\GoogleDCC\GoogleFAH, from what I can tell. Unfortunately, it seems that the assignment server is presently FUBAR and it won't get any work right now, so I can't tell for sure that this works 100%.

When I changed the team number both in registry and also in the client.cfg file, it does start up for team 93, which is what I edited it for, since this rig was already folding for them before I started experimenting.
I've zipped up and attached the fahlog out of google's install so that you all can see what comes up when I played around with the team #'s in registry and the client.cfg file. Now all we need to do is have someone write a harmless little virus that automatically changes these team numbers and spread it on the net.

Seriously though, you should be able to borg anyone's computer to the team of your choice when you run across a google toolbar with google compute running on it.
