Multihoming: Restricting an app's access to some IP's

[Kenneth Porter <shiva@xxxxxxxxxxxxxxx>]

Is there any way to set user or application access control on the 
interfaces available? I've got two public interfaces on a hosted server, 
and some dumb apps (closed source game servers) bind to the wildcard 
interface, so they end up announcing their existence on an interface I 
don't want used for that service.
