hi
During some technical rambling, ran into this...
http://code.google.com/p/rlz/wiki/HowToReadAnRlzString
Apparently, the default google chrome install has this string setup in some options, which kind of puts and "ID" on the installation of the google chrome.
So if we were to use the same browser installation with our hobby ID and our real ID, to login to google at different(exclusive times) google on their end can still see that both our real and hobby ID's come from the same installation of the chome browser...
Any experts can shed some more light on is my assumption is correct, and if this sort of ID can be used by other non-google websites also (who use the open-sourced rlz library?)
