Hi Steve,

        I don't quite know how to respond to this!  Your statement is true
given some assumptions, but not relevent to my implementation, hence the
presence of your assertion in this thread is quixotic.

        In my implementation, you can't tell which domain on the LAN a packet
came from, nor do I try to prevent malicious domains on the LAN from
effectively stopping all useful traffic.  I believe that multi-domain
access is useful in some scenarious, nonetheless.

Hope that clarifies?
Rusty.
