Couple of comments:
1. Should the "plugin" (if one can be created) also record audio at the same time? That is, if you are having a conversation with webcam AND audio (or a videoconference), should it record both video and audio? What about just audio? Should the plugin also allow for that?
2. As already mentioned, I believe any "plugin" should notify the other person through the MSN chat window that their webcam session is being recorded. It could even go so far as to send a message saying that the recording will begin in 10 seconds (and to "stop the webcam if you do not want it to be recorded"), then another saying when the recording has started. This would give the person time to end the webcam session if they don't want it to be recorded.
3. With regards to other programs, I believe it would be easier if this fuction was accessible from within the MSN chat window. It would also allow for Number 2 above, which I think is very important.
They are my thoughts.
