I don't believe you'd be able to use GRE tunnels, as they are not an "Ethernet"
type of tunnel.
However, I run a network with three physical locations, bridged over TAP-type
tunnels using VTUN (vtun.sourceforge.net). These are Ethernet-type tunnel
devices, so the bridge code just sees them as if it was any other Ethernet
network interface.
In addition, I use ebtables to control what traffic gets bridged across the
tunnels, so extraneous broadcast/multicast traffic stays where it is supposed to.
