A good non-technical solution to this problem is an intentionally slow/standard Internet connection, such as at my cafe of choice.

For me, it is frustrating to be at this cafe at peak laptop hours and I think it causes people to churn in and out. So, I try to only use my laptop there when there are fewer laptop users at the cafe. I think this is a good psychological effect for the cafe to impart on its customers!
