no, I don't believe its a subdirectory within the server. Google offers so many services, one server would become very crowded very fast. ------------ Setting up a cookie/session for each domain at login is an interesting idea. And I do believe I see some things similar to this happening.
What if I have 100 domains? I may not want to establish 100 sessions/cookies. Just allow the user into one of the other domains as they feel the need to hit those other domains.
The insights have been great. I've started calling what I'm asking for "multiple domain session" and googling that has yielded some results. I look forward to your help in clarifying this further.

Assume that there is a YouTube video embedded on a web page. Before you even click to view the video, you get several YouTube cookies.
About ten seconds after you click and start watching, the Flash code behind the YouTube video phones home to google.com and your standard Google cookie with the globally unique ID is offered up to Google. By watching it on a packet sniffer, you will see that the GET request from your browser to google.com includes the URL of the page you are on, as well as the ID of the YouTube video you are watching.
It happens on Obama's change.gov site, as well as on youtube.com itself. It happens everywhere you see an invitation to watch a YouTube video.
