It very much depends on how the connection is made.
If you use a scure "tunnelling" connection, probably not.
If you're just broadcasting a video stream from the host machine, then it's wide open... assuming that somebody at the ISP has nothing better to do, or is psecifically intent on montorng your individual activity.
An analogy might be that, yes, the guys at the mail sorting office, could, in theory, be reading your mail... but why yours, out of all the millions?
If you're not doing anything that you need to hide, don't worry about it. If you are, invest in better technology.
