Customer == user with money to give us :-).

Well that's certainly the right attitude :).

Tricky. What you probably need is something like gdbserver that listens on
a socket on one side and uses the GDB remote protocol to talk to GDB
through it. And then on the other side talks RDI to Jeeni. Once you do that
first stage, _then_ we can worry about thread debugging.

But it's several weeks of dedicated work methinks if starting from scratch.
