Try watching your network traffic using tcpdump. I think you will be
surprised.  The Linux bridge should be acting as a switch, detecting
that the MAC address of MachineA and MachineB are local and sending the
packets directly.  I don't believe it will send it all the way out to
the ISP.

That's how I believe it works, anyway.
