If any of you want _another_ satellite...

[Robert Stratton]

you may have a chance. 

There's an open hardware project on kickstarter. $300 will get you a board with a microcontroller and a radio and the ability to program your name and a short message into it. The plan, by a grad student at Cornell, is to pack a pile of these into a Cubesat and  scatter them. He plans eventually to get to putting local sensors on board and perhaps fabbing a custom chipset to bring the cost down. 

It sounds like he's trying to coordinate with NASA's Educational Launch of Nanosatellites program, but it's not clear that he's depending on that working out.
