Multi-user switch widget?

[squirrelproductions]

I know that the lock-screen is just a click of the power button away, but I was wondering if there was a widget that would allow for quick switching between users in a multi-user scenario (as in JB 4.2 tablets like the Nexus 7). I'm finding that I have to readjust my hand that is supporting my N7 and then click on the power button to access the lock screen so that I can switch between users. A widget would allow me to bypass having to click on the power button.
