I actually predicted this about a year ago, and wrote a blog series about how to set one up yourself with generic scripts (later collected into an ebook here http://hunterdavis.com/build-your-own-distributed-compilatio...). It was featured a few times here on HN. Cross compilation can actually be quite speedy, but speed isn't the only reason to use such a machine, especially in a business situation.
