Wow... I'm completely amazed, no idea that this project existed. As you
say, it's similar to the (very) advanced LA offerings for in-FPGA debugging.

Yup, seems like a good way forward.
What's needed here is for some FPGA projects to incorporate chipspy into
their projects, providing sigrok with an "excuse" to support it.
I'm going to ask some FPGA developers about this and see if they're
interested. If anyone knows projects that could benefit, please do the
same. This is potentially awesome for chipspy + sigrok + open source
