You'll want to implement your own session handler and store the data in
a database. Then you can access and load the session variables from any
domain with access to the database.

If you want a "remember me" feature, then you'll have to implement
something with cookies. Sessions will remain active as long as the user
is active. If they are inactive for a certain amount of time (which you
can set in php.ini) then their session file will be erased. 

Hope that helps.
