Definition of multi-principal (as I understand it)

Today when you use a browser, all code that runs in your browser's process runs as "you" -- your user account in Windows or whatever OS you're running. (In Protected Mode IE, it is a restricted token, but it is still fundamentally "you".)

Multi-Principal essentially means that when you browse foo.com, instead of the process running as "you", it runs as user "foo.com". Browsing bar.com runs it as user "bar.com". Thus you automatically get all of the OS's security mechanisms for separation of user privelege.

Of course since today's mashups depend on communication between different domains, you need to have someone (Gazelle's "browser kernel") brokering the communication between these different processes.
