-  Can use the code from netbeans to communicate over a socket.
-  A bit like +clientserver but without the hassle of starting another Vim.
-  Use json for the messages.

-    call sendjson(handle, {json}, {callback})    # async
-    call sethandler(handle, {callback})
-  The response json is wrapped in an array:
-    [{code},{response}]
-    {code} must be positive, when zero the callback from sethandler() is called
