It's said that it can already execute such large projects as Eclipse. Has anyone tried that and can compare the performance (and the memory resources it needs) to the Sun VM? I would love to see a VM which takes less memory and has better performance.
Can the JVM bytecode and the .Net assemblies somehow magically make use of each other or do you have to choose which one you target? If you can't this seems to be "just" an implementation of each platform, right?
