The SF office has a street-level room set aside for use as a community space, theoretically it shouldn't be too hard to convince them to let you use it. I know this because I intend to use it for various Rust-relates purposes for the next month or so. :)
Thanks for the info. I got too busy and stepped down from the Meetup group. I encouraged Mozilla to take over as organizer, but they didn't. I hope that someone else will start one up.
