Hi Shawn This sounds very good news. I'm eager to test it (currently I cannot because not at home) I had previously tried this project: https://www.hackster.io/markkomus/using-a-raspberry-pi-pico-as-a-logic-analyzer-with-pulseview-e12543 But as said by the author himself it was quite limited because the output is a csv file, it isn't a sigrok hardware driver. Worth to mention this project as well : https://github.com/pschatzmann/logic-analyzer I never tried it (because his own arduino lib) But yours sounds better because it's a real hardware driver for the pico. So we can get pico 120MHz !
