The floor shouldn't pose any problem for multiple users in seeing or interacting with the environment correctly. There are several options for moving the user that are elsewhere in the thread (moving tiles, treadmill-like solutions, etc.).
The only issue I could see would be in interacting directly with another user. With close physical proximity, they would of course always be visually close as well. I can't think of an example where this would be an issue, but if it was you could always just put the other user in another location and use an avatar!

One thing I would recommend is going with glass filters instead of plastic. The plastic do a little better job of polarizing, but they burn up really easily. Also make sure you are cooling your projectors well enough...
You can set up a similar active stereo system that will let users walk in different directions and still see the appropriate images.
You just make them time sequential and sync the glasses accordingly with optical tracking (User1 L-Eye, User2 L-Eye, User1 R-Eye, User2 R-Eye).
