I've been looking for this... pay through twitter. Imagine the possibilities!

Running Lean was a book that you could pay with a tweet: http://www.runningleanhq.com/

Not the same thing. That is the author trading retweets for a book. Sell Simply actually turns Tweets into transactions. You can pay, buy, sell or donate with them.
