I don't know how much of wine's source would need to be changed to
disallow all network commands, but I know that this kind of thing is
possible using iptables (particularly with the owner extension).
If you create a new user id (which will be the one you use to start
the application, using su or sudo), something like 'nonet', then run
iptables -I OUTPUT -m owner --uid-owner nonet -j REJECT --reject-with
or something like that (I haven't tested it), it will block the
'nonet' user and any applications started as it from sending network
