Tim Kadlec has put together an awesome little site called What does my site cost?
It mashes up data about your site from WebPageTest.org with average data costs around the globe and financial metrics from the World Bank to provide you with a few different views of what your site costs to visitors around the world.
When lobbying for performance, this is nice, tangible metric to share with clients.
