They'll be bared from entering into a rounded orbit.
You jest but a Boeing patent on a specific satellite manuever had the effect of decommissioning a satellite. http://www.google.com/patents?vid=6116545
I worked on this project for a few months. We ran everything like a typical agile startup with weekly iterations and a lot of testing "MVPs". Really cool project. Also its all going to be opensourced! http://open.nasa.gov/plan/phonesat/

That's awesome! Is following @NASA_Phonesat the best way to find out when that happens?

Of lead? At $10,000/lb launch cost?
Lead wouldn't work anyway - it would make things worse actually. Lead is good for gamma (and X) rays, but very very terrible for cosmic radiation which is protons and neutrons (nucleons). For those you want water. It works like this: For photons you want them absorbed, so heavy metals are great. But it's not possible to absorb nucleons. Instead you want to steal their energy. If you use lead they simply bounce loosin…

You've written an incredibly interesting comment addressing something I had no idea about, thank you.
Shoot various size coins at each other and watch how they interact, then try a coin against a wall.
If you have a very slippery surface try making a line of 3 coins (or more if it's super slippery) to bounce against each other.

You can get an injunction against self-driving cars that can do the newly patented three-point-turn (its not prior art because now it uses a COMPUTER system!), but you can't stop a driver from doing it!
Why is it important to make satellites which are cheap to build? Isn't the total cost dominated by the cost of bringing it to orbit anyway?
They are tiny as well, so in one launch you could put a LOT of them up there! For some kinds of operations, it's better to aim for 95% reliability and put quite a few in orbit, than to go to the expense of 99% reliability.
