Mind you, since Google is already personalising based on IP, perhaps as much as you try to keep accounts unrelated, it may not be possible unless proxy is employed too.
...we're introducing a new, simplified workflow that allows you to toggle between multiple Google accounts without having to log out and back in again. With this update, you can now:
+Manage multiple AdWords accounts simultaneously in the same browser
+Stay logged into multiple AdWords accounts or other Google accounts at the same time
+Save time switching between accounts with different logins
