SO_BROADCAST support was added to nsock, but is off by default. From 
nsock/include/nsock.h:

   /* Turns on or off broadcast support on new sockets. Default is off
       (0, false) set in nsp_new(). Any non-zero (true) value sets
       SO_BROADCAST on all new sockets (value of optval will be used
   directly
       in the setsockopt() call */
   void nsp_setbroadcast(nsock_pool nsp, int optval);

nsp_new() is called for NSE in nse_nsock.cc in luaopen_nsock(). To 
enable broadcast, a call to nsp_setbroadcast() must be made after that call.
