You don't mean changing one MAC address in Gigaswitch configuration is a
bolder feat than swapping (failed) equipment, do you?

Problem is that if hardware fails or is swapped out, MAC addresses change.

Isn't it possible to filter MAC addresses at Gigaswitches?

Apparently people are still missing the point. On a shared media

So far from what I have gathered, everyone is afraid of being used as a
transit point. There is a very simple solution available which I can't
figure out why people are not using. 

Both peers charge each other for the bits being peered. So now if one
peer is being used as a transit point, then they get compensated for it. 

Eg

AAA               BBB
15443621 bits ->  15443621 bits
20000000 bits <-  20000000 bits


Difference 4556379 bits additional sent from BBB to AAA

Applying lets say 1 cent per  100 bit charge, AAA gets $455.64 from BBB

Simple!!!!

Now with this kind of peering arrangement, no one has to be worried about
being used as a transit point -- infact they will want to be used as a
transit point. 

This will also allow medium sized ISPs to peer with each-other. 

So here is my question -- why is this kind of arrangement not being used
anywhere???
