Make a Signal Generator with a Similar Architecture (USB Driven)

You're half done. I love your architecture (use the PC's memory and computational power coupled via a USB to a relatively small device). Now just add a signal generator.

For the first product, a separate signal generator would be fine. But eventually make a "Combi" with a logic analyzer and signal generator in one package (and one USB connection).

    With something like this, if we had the ability to output a pattern to each, or multiple lines... perhaps we could create some software that mimics the "JTAGulator" by sequentially reading what's at each test point, then injecting each suspected target point with a pre-defined logic pattern at various rates until the Saleae Logic detects the appropriate read back for that test point.
    Further, if we had the ability to take this new device out of "generator mode" and send signals from the host computer out through this Signal Generator, we could then use our custom software to create our own JTAG auto-detecting in-circuit programmer \ debugger! Right?
    ... Or ...
    Am I so lost I don't even know what I'm talking about?

    I would add a logic pattern generator which can take the logic analyzer data captures and play them back.
