when we did it for our AR game, we used UNET - so I would assume Mirror should also be able to support local wifi. I think the way Jackbox typically does it is through NAT punchthrough, where you connect to the server and that server connects everyone to each other. I ended up cutting when I mentioned that in this video for time and I didnt run into any solutions, but that is what I would look for.

glad it helped :)

kinda depends on how complex the POC builds are, but generally speaking, assuming you have abstracted out the networking correctly, then it should not be too complex to swap between SDKs under the assumption the services have similar features. but if you are just passing messages between players, that makes things a lot simpler.

depends on how far along you are. not the most straightforward thing to do
