Really depends on what you're building!

Answer 3

I am author of jni4net, open source interprocess bridge between JVM and CLR. It's build on top of JNI and PInvoke. No C/C++ code needed. I hope it will help you.

Answer 4

alternatively you could write a webservice/xmlrpc layer between the two.

I seem to remember that there is a tool calles grassshopper that will compile your .Net code into JVM bytecode.

I've also heard good things about IKVM
