Linux controls suck for this. Currently what I do for Neverwinter Nights is
run it under a separate user and use firewall rules not to let it send
traffic over the external interface.
My preference would be to run it as myself, but limit its network and file
access.
I also have a couple of games I don't play too often that use wine and I
haven't put effort into locking them down yet. I don't know enough about
the wine environment to know how easy this is to do.
