how well (overall) does the partially in person/partially in "zoom" work? I might have to do that for one game, but I wasn't sure
IME it works well, but there's a few tricks and considerations to making it work best. As well, the ease of doing it varies depending upon whether you're running entirely TOTM or using maps. Regardless, I always run 2 instances of the VTT. One is my GM instance on my laptop and the other is a pseudo-player instance that's displayed on the big screen. TOTM is the simplest and I just display the VTT's feature for tracking combat order/initiative and ocassionally share images on the big screen. That makes for a terrific tool for displaying/managing encounter order at the table, while allowing the remote player to see the same. I have a mic and speakers at the table that are connected to the same Discord chat channel the remote player is.
When using maps, the big screen is a pseudo-player's view and I have the pseudo-PC's token on the map. That gives the in-person players a view of the map and shows where the remote player's PC is. If it's a setting in which some have the ability to see in the dark, or one with varying degrees of lighting, I compensate. In that I have the pseudo-PC match the party's PC with the best capability in sighting or lighting, and move the Pseudo-PC token where that PC is on the table.
My goal in doing all this, is to make the in-person table the primary focus and have the VTT a secondary, support tool. So, I'm hesitant to place in-person player's tokens on the VTT map. I find that in-person player's can become too distracted by the VTT map, viewing it instead of the table. That said, there's some situations where all tokens on the VTT is optimal, if not necessary. I.e. I run a SciFi campaign with Alpha Strike (simlpified Battletech) rules for combat. It's miniatures heavy for table combat and we play with a lot of 3D scenery props. For that it's better to have all Mech tokens (PCs and NPCs) and scenery objects on the VTT map, due to considerations like synergy, cohesiveness, sighting and demolished structures.
I also discourage mobile phone or tablet connections to the Discord channel, as I find it too much of an invitation to side chat. I have USB/XLR omni/directional mics, good portable speakers and a portable media interface - all of it fits into a small pack. So, even if I need to host at a different location (i.e. player's home or FLGS), I can provide all the audio needs. They just need a HDTV, or big computer Display that I can connect to.
