I can't say if BSD is picking up on Ethernet hardware addresses
from the incoming connection request, but there is no reason why
this can't happen.  The internet address of remote end would be
entered into the arp cache with the gateway's hardware address.
This will work.  This is how gateways on Ethernet subnets trick hosts
that don't know about subnets into working properly.  The gateway
sends arp answers for IP addresses off the local subnet that it will
route for.

Nearly every device I've come across (including BSD UNIX systems
and other things for which we don't have source) will allow manyone
mappings of IP to Ethernet address.
