I've heard of bathroom fans which have the blower at the top of the

multiple bathrooms with one blower. But I'm having trouble imagining
how that would be wired so it could be turned on in either of two
bathrooms. That's not a three-way switch.

Right. It's not a 3-way switch. You'd wire two ordinary (SPST)
switches in parallel. Use only one circuit to supply power no matter
which switch is being used.
