Not sure if that would be possible. I did some google searching and didn't see anything that could be used to distinguish a client side screen sharing from other traffic. My guess is that once a client connection is established, all data is sent over that connection, so blocking the screen sharing would require the ability to decode the established data streem. That doesn't seem likely.
I'd recommend contatcing Goto Meeting support for some advice.
