you wouldnt have to do any of that, all you would have to do is make msn messenger automatically perform the command sent to it through a conversation window if the password is correct.

so you just need to make a plugin that understands the command, and can make messenger automatically perform the command, which should be very easy because you're not adding any new features, you're just making msn do what it can do already, but then you're making it do it by itself, like a robot.
