I fail to see a way how the server can give any particular useful hints about 
the cookie like "This is suitable for a tab" or "This is for a whole browser". 
After all, I would figure a browser could decided to do more or less *ALL* 
cookies separate in their own tabs.

The problems for a browser inlcude how to know what cookies to save and which 
that would be used globally etc. I would assume that it would make separate 
cookie jars and let the user match jars with tabs or something. And possibly 
make one of the tab's jars become the global jar...

I don't think this is a HTTP(-bis) issue. Even if the http-state list is 
mostly dead...
