Ah I see... I might check whether this .NET > Java project is worth using, but I'd much rather not. If the net protocol was just published then I could probably write my own .NET interface for it, as long as it's something fairly simple like plain TCP/HTTP post/maybe even SOAP.

There are a number of projects out there which allow you to call native functions from Java code, using JNI. So you would implement the interface with one that calls native functions.

If that's how you like to write your code, sure.
