yeah, I'm familiar with those tools, and other teams at dropbox have used TLA+ for verifying their protocols, but we haven't done it for our system yet. we've spent most of our time on testing working on better randomized testing, with the idea that covering more surface area there has higher ROI. but I can definitely see value there, especially once the protocol "settles down" and sees less change over time.
