.. so, the "dst not for me" check in the above code gets a little more complex...

You can put the filtering into the foo_forward functions (i.e., block
IP and ARP since you want those to be routed).  those functions have
to understand and rebuild the link-layer headers anyway (since for
bridging between regular ethernet and something which uses LLC headers
-- e.g., an 802.11 AP implementation -- you have to insert/delete SNAP
headers).

Care to outline in a little more detail how you'd structure the code?
