Oh my god, thank you for mentioning this project. I just deployed ZeroTier for some local infra, but in doing investigation, I was desparately trying to find the Nebula project name and GitHub. I was looking for "beacon", "lighthouse", "bastion", "ZeroTier compete" and everything in between. I even knew it created at some prominent tech company (kept thinking Netflix, of course it was Slack). I was starting to think that I'd concocted a false memory and it didn't really exist.

So now I gotta go decide if I want to rip out all my existing ZT infra or not.
