GPL Shopping
I moved houses, but not my whole network setup, so I needed a little router to connect all the machines I already moved. Walking into the store the first router box that I saw had a big GPL-Inside sticker on it! How have times changed. Apparently having the three letters G-P-L on your (hardware) box is now an extra incentive for your customers to buy your stuff. Very nice. And routers these days are really full general purpose (MIPS based) computers. For this one (and others) there is a whole community creating alternative software installations. OpenWRT even includes JamVM and GNU Classpath (now how is that for an incentive to work on JamVM Robert!)
