That would be very unusual.  Unless there is an IP routing entry in
the hosts's IP routing table that points to the local LAN, it should 
never bypass this and go directly to the ARP cache (whatever is in
there).

You can easily verify this using traceroute, though.

Unlikely (well - there are switches that do that, Cisco MLS for example,
but that's not a standard approach).
