Dan,

I've never heard of Dave Bogg's story, but it probably would not apply to
the non-consumer radio community today anyway.

I'm not sure I understand what the gateways can do to ameliorate the
the problem that (some) hosts do not understand subnets, other than in the
special, but common, case of Ethernets, where Noel's suggestion might in fact be
incorporated in the present gateways without too much trouble. His technique,
which I have called "promiscuous ARP" is used in our gateways as well.

As for advanced models, you may wish to see the document NEWMOD.DOC in the MILLS
directory on ISID, which describes one possible scenario supporting mobile hosts,
multiple-destination, multiple-path routing and serves ice cream for dessert.

I suggest further discussion on this topic be switched to the tcp-ip repeater
or direct.

Dave
