Or brand a US-based proxy server as a way to access geoblocked stuff :-) $5/month should be enough to proxy a chunk of multimedia through US-based servers, and I know people who would pay it.

I'm only semi-joking. I can't convince myself that it would be ethical to do this, but I'd like to see it happen as a way to get people talking about geoblocking as something that incurs a cost to Canadians.
