An alternate take:

Each deck will have to do its own collision detection for the "room"
its user is currently in.  Each object will have its master copy 
on some machine, and representative copies in each deck that happens
to be in that room.  The representative copy can be read-only or
read-write.  If read-write, it can be altered in the remote deck
and a report sent back to the master.  The master can
accept, reject, or consider several competing reports and
average them.  It can send out its own change orders, which cannot
be ignored.  If read-only, messages to the remote object do 
nothing to it, but are forwarded to the master. 

Consider modelling a game of fragile bumper-cars.  Remote bumper-cars
are read-write in your deck, and when you hit them, they dent.
They also tell their masters, "Ouch!  I've been hit and dented!".
They don't break; that takes a change order from their masters.
