As a contributor to the Apache Software Foundation's Karaf project, I've set up a virtual appliance for folks who want to do OSGi development. The feedback I'm getting from the community indicates a strong preference for IntelliJ over Eclipse, which is currently installed in the vapp.
Does the IntelliJ IDEA Community Edition's license allow for it to be packaged into a virtual machine? The VM will be very visibly branded as containing the IntelliJ IDEA with links allowing interested developers easy access to upgrading it to the paid version. Because this VM will be the first OSGi development VM available on the VMWare Marketplace, it will provide IntelliJ access to developers who work inside of cloud environments.
