Good to know. Thanks for the link.
For anyone, like me, who is more than a little nervous to share a session during something like a Meetup session given that the current Fleet terminal tool exposes great risk, I would recommend the following work-around for now: create a dumb user on your hosting computer with no admin privileges and copy your shared project into that user's home directory; then fire up Fleet as that user. Any malicious collaborators should only have a minimal opportunity to cause serious damage and/or problems. Similarly for non-malicious but accident prone collaborators.
