I need to open two instances of a browser, one as one window as a user in the system with one login and set of session variables, and the other as another user (usually a manager) to manipulate the system through the ZMI. Likewise, sometime is is useful to open two instances of the system so that you can look in one place with one window, and in another place in the other.

Set up different user accounts on the machine, then run two instances of the browser using different accounts. Under Windows 2000/XP, hold down shift, right-click on the shortcut and choose "Run as". Under Linux, use "su". Should do exactly what you want.
