Anyone now how to create custom signatures for streaming audio and video?
I would assume that I could create custom connection signatures for specific ports for each of the streaming services (i.e. RealPlayer, PointCast, etc...), but I was wondering if anyone out there has already done this and if so, what ports were you keying on? If you have any, would you be willing to share them with the rest of us?
Or maybe, this is something better left to a filtering device...I don't know.
