sorry about the cross-posting; i first posted in one and then i realized (or assumed) that the people that would most likely know about the subject was in the other thread group
btw, i did
ifconfig etho down
ifconfig eth0 hw ether <newHWaddr>
ifconfig etho up
it worked beatifully!
with hostname command i changed the ..um, hostname, and the inetaddr can also be changed straightforwardly with ifconfig
..as expected, i lose connection and had to reboot
maybe i could configure eth1 to point to the same device, but that just sounds too hacky
cheers!
