OK follow up.... tried on the local network.

Assuming you have sudo rights on the machine, and don't know her password:

sudo -i   #gives you root

# su <her-username>  ( since you are root it won't ask for a password)
( you are now "her")

gaim --display :0 &


(you are now root again:  exit again to become "yourself"

This appears to work :)  Apologies for the convoluted and inaccurate
previous post!
