In the book, 'The Lean Startup' author Eric Ries actually used this strategy for his messaging company IMVU. Essentially he wanted to do the same thing I am doing, but for MSN, Yahoo, Aim, etc. It ended up being a catastrophic fail in one of the most read books in the startup world. Can you blame anyone for not trying it?!

Though this isn't where I got the idea, I read about it the other day when I had some downtime.

I accept your challenge and will prove the future is in fact quite bright! :)
