W3bbo said:The JVM has been a multi-language VM for some time now; for example there's Groovy and a whole load of others, including a C compiler.
I don't think Sun capitalised on expanding the JVM's language range as much as Microsoft has.
yeah, I am aware of that actually 
what I meant is that, instead of the language guys trying to adapt the vm, the vm guys are actively trying to adapt more different kinds of languages, with JSR292 (invokedynamic) and other stuff,and the effort is finally
going to fruit with the coming Java 7 platform, while MS is backing off from the Iron-languages.
but, the latest issue of MSDN magazine has articles about IronRuby and IronPython, what could that mean 
??
