It's my personal site, experiments like this are why it exists :)
As far as costs go, my Rackspace VPS was $11/mo. Given that I get close to zero traffic and CF is $0.15/GB, this will cost less than $1/mo. I'd say that's a pretty good price for having my site hosted on a high performance CDN with points of presence worldwide.
Surely there are simpler and cheaper (free?) solutions than this.
