One of the things we are doing this year at JavaOne is giving away CDs of Eclipse SDK 3.2.3 running on a milestone release of the Apache Harmony project. We ordered 1000 CDs but have already run out. Lots of people are interested in learning more about Harmony and how it works with Eclipse. If you did not get a CD or were not at JavaOne, you can always download it from Sourceforge.
I think this is a great example of Apache and Eclipse communities working together.
