#49 [privacy] sandbox cookies for different google sites

[ill]

The ability to be on a different user account to different google owned sites, defeating their attempt to link information about you into one database. So you could be logged in as a certain user at mail.google.com, and then as a different user to youtube.com and not have that account linked to the account at mail.google.com. Each separate google service site would see a different set of cookies and not know about what you do on their other sites.
Given googles recent privacy change, this seems important.
