This is cool and all, but if it's called a "linux stamp" it should at least have some I/O capability other than a serial port. (I am thinking of "turn on the LED" type things.) The basic stamp does really well here, despite being proprietary, horribly limited computationally, and locked-in to one of the worst programming languages ever designed (PBASIC). I remember it offending my sensibilities even when I was in middle school :)

Programming I/O in Haskell would be fun. What would you call the "turn on the LED" monad? :)
