Get remote screenshot (without logging in)
Download a screenshot from a remote computer without the need to login.
This could be very useful for a quick check of stand-alone computers (kiosk, digital signage, etc), where actually logging in could interfere with the current users of the computer (and at least shows the users/observers that something is going on).
If this could be automated (e.g. a screenshot every 5 minutes), this would be even better.
