Looking into Amazon even, their prices are fractions of a penny on bandwidth. And I see reddit dump all their servers, drop employee load, and it seems the home garage is rad for testing, but maybe not that great, as one day, if it all works out, you have to retool for the cloud anyway.
P.S. I am doing hosting of non critical stuff myself on a Comcast 50/10 line which is really 60/15, on a few mac mini's, which use near no power, and seem to stay up pretty well. I am just toting around with my personally ideas mostly. I like the fast local lan access, and I jump to a VPN so I can feel it like the rest of the world would. But it is only temp, until the idea proves viable, and then off to the cloud I go.
