with respect to directed broadcasts (subnet directed broadcasts), I have
now determined that Linux does not allow them.

The code is in linux/net/ipv4/ip_input.c.  All broadcasts are dropped when
it comes time to check forwarding. 

I have a hacked up version that allows directed broadcasts that I will be
testing soon so I can check out remote announce stuff ...
