Q: Running hybrid AD&D game: virtual+in-person?

(Also asked this on the r/OSR subreddit...)

Thanks to COVID, I had to put my long-running, in-person AD&D campaign on hold. So two years later... I'm looking to start things up. Finally!

Problem is, one of the longer running players who really contributed a lot to the campaign has moved across the country! And he's asked if there's a way he can participate.

So while I have done hybrid meetings at work with meeting rooms with huge wall monitors and tracking cameras, I play my in-person AD&D in my gaming room in my basement. I don't quite have the $$$ to put something like that in.

So have you run an AD&D/OD&D style game in hybrid mode - with people in person and virtual? How did you set it up? How did you deal with situations when the minis come out, for the virtual folks? What should I be thinking about or anticipating facing?
