Google Invisibility Half Scan

Google Invisibility Half Scan helps you find out if your Gtalk buddies are invisible. To do that it sends a presence probe to the buddy. If there’s no respose before time out expires, then you can establish that the buddy has no active resources (and therefore he should be OFFLINE).

If you get a presence of type ‘unavailable’, this means that the buddy has at least an active resource (it could be a Gmail or iGoogle page opened with chat turned off!) and therefore COULD be Invisible (at least you know he or she is connected).

This is an “HALF SCAN” because you can not establish with certainty that a buddy is invisible.

Note: For the moment, the bug this plugin exploits has fixed! So at this current state of development the plugin is no longer working.
