I am talking about a way to intercept webservice calls,
not method calls.
This can happen inside or outside the server.

Thats ok,
No, intercepting methods calls in one vm is not the plan for this
debugger. Of course it would be a powerful tool to be able to intercept
any call to any function, and even apply security aspects to each
function call. But this is what we considered to be overkill in our
last  discussion.
