So the birds tell me that cool things are going to be open sourced by Sun this year (like javac), and then a big pile next year. And ME too!
It will be interesting to consider their javac in Harmony, compared to the Eclipse one. Sun has a chance to one-up Eclipse by using a license with less restrictions, like a BSD license.
