This is very interesting, it will make Java even more popular than it already is.  My question though, is how will this affect compatibility and inter-operability?  My experience with several Java-based tools at work indicate that Sun had issues keeping new versions of the JRE compatible with previous ones – or at least developers were using features of older JREs that didn’t work when you installed the newer ones.
