This software for the Mega Squirt has a good display. It is also tuning
 software but that does not have to be used.

 Many Andriod tablets can be "rooted" and a version of Linux installed.
 The software connects to a computer via a USB cable.

 I also ran across this software. Although it is not open source, the
 price is reasonable.
 An article about it is the current ( August 2012) issue of Nuts And
 Volts magazine.

Fortunately, my Acer A200 has the Android USB Host capability along with an
micro A/B and an A type USB plug.  So I can hook my PC to it to load the
Android code and then use the second USB port to talk to an USB-Serial
MCP2200 translator chip on my project board.  This precludes the need to
"Root" the tablet.

First, had to learn the USB layered protocol and then find/build code to
step through that to find the USB endpoints and finally  work up code to
transfer data from the project board to the Acer tablet for display.
Finally got there, but the learning curve was pretty intensive.

What is the final product Ed?

Send us a brochure :) Can you get data out of Tracy's computer to the tablet?
