Imagine you have 20 Friends in your list (or nice girls you know
).
Many people only connect the cam for a short time and plug it off.
So i would have to open all friends to see if the icon is there
every half hour or so.
But with a plug-in that checks if someone attached his cam,
i will be notified immidiately and can ask for a session or simply
know that the person is using the cam with someone else.
