James,
If you have or can use a SWF compiler program, I'll have the code done for the MDI for Flash screens in Mach within the next few days.
If you don't have a SWD compiler program we'll have a number of screens to chose from,actually the setup you want will be one of the first screens we'll have. I should have some time tonight to finish the code and construct a demo screen for you to test.
If you would rather not use Flash, Art is working on adding this to Mach in the future. Currently there is a calculator for DRO's in Mach and this will be adapted for the MDI as well.
If you want send me a sketch of what your thinking for your screen
