Total guesswork here...

In the BSD man page for sendto(), it seems that broadcast datagram 
sends have to be explicitly enabled by the caller with this flag

#define	SO_BROADCAST	0x0020		/* permit sending of broadcast msgs */

  [EACCES]           The SO_BROADCAST option is not set on the socket, 
and
                         a broadcast address was given as the 
destination.

Can't confirm, but I don't see equivalent options in the Linux man page 
for sendto(). Guessing maybe Linux doesn't have the limitation.

How this information relates to the Rev engine I guess scott or tuviah 
could answer.
