Well, there is a finite amount of physical space in the actual room, though the room is still quite large.
As far what type of installation, it can be anything.
The only thing I would keep in mind is possible sound bleeding, especially if alot people participate.
That could mean having headphones to use or building a sound box that only one could stick their head into, or even taking the time to construct as some enclosed closet/room for people to enter.
really, the possibilites are endless.... which is what makes it challenging.
