I've experimented with this before, with two PCs connected to the same
switch (I forget the make, it was a cheapo model), both with the same
MAC address.

The two PCs could still browse a remove website, but at a much reduced
speed. It felt like going through a slow modem. I had the feeling that
packets coming back from the web server were being randomly sent to
either PC.

Depending on the infrastructure, both you and the spoofee may still
get service, but it might be pretty slow.
