Java.NET?

I wonder ... I wager it is just a matter of time before a compiler that can take java source code and spit out MSIL will make an appearance, as is one that will take .NET source code and spit out java bytecode.

Better yet, a cross compiler that can take MSIL and spit out java bytecode (cutting out the horrendous task for catering for VB.NET. J#, C#, Cobol.NET, etc, and going right to a unified MSIL), and vice versa. This will be a killer tool that will enable you to use a java class from a .NET app and a .NET class from a java app. It's bound to be quite an awesome beast because it will have to cater for features that are in one language but not the other and substitute viable workarounds (particularly the totally different event handling mechanisms). There are huge implications to something like this, but if man can go to the moon, this is a distinct possibility.
