MSN MESSENGER 5.0 WEB CAM PLUG-IN
MSN Messenger 5.0 has already a feature for video conversations however, like with most of MSN Messengers standard features, they all try to communicate directly with their clients, which results in the video data or whatever is usually being sent, is stopped dead in its tracks by things like firewalls or ICS setups.
So what's the solution to this... well Logitech and Microsoft smartly came up with a plug-in for MSN Messenger that uses a web server to act as a third party handler of your MSN Messenger data, in this case video transmissions. This therefore allows MSN Messenger simply to bypass routers and firewalls for the purpose of a video link. This particular plug-in requires all partys to have it installed, but comes with the added benefit of making your video, or more specifically your webcam broadcasts accessible by more than one idividual at a time.
This particular plug-in is an exmaple of the direction Microsoft plans to take MSN Messenger in the future, using it's own servers to help the advanced functions of Messenger to work more efficiently. The file transfer functionality I believe is one feature which is due to get the same treatment in the near future.
Please also note, this plug-in only works with MSN Messenger and not Windows Messenger and also this add-on now comes built into version 6.0 of MSN Messenger.
