Tablet PC as remote CDU for PMDG 737

Hi everyone, I was wondering if there is any way of using my old tablet pc as a remote CDU gauge for PMDG 737. My tablet pc has 8" touch screen, network adaptor and runs over windows 2000. I have already tried Maxivista and everything was fine except that I couldn't use the touch screen to enter commands (only by mouse or keyboard from the server pc). I asked Maxivista programmers and they answered that it is not possible to use client's touch screen or keyboard and they say they working to find a solution for this. I hope they will come up with something... I checked also Project magenta but it is very expensive for me, also they say it does not work with PMDGs. I also tried vasfmc but It was not what I was looking for. I finaly tried P8R CDU which I liked most but it doesn't seem to be compatible with PMDG A/P....
So, are there any other ideas? I would be very glad to see this working...
