Yes, that works for me. Further, this works when run from a different 
machine on the same network:

echo "UDP broadcast" \
| socat - UDP4-DATAGRAM:255.255.255.255:29531,so-broadcast

Examining the packets as they are captured by tcpdump, both the ones NC 
sees and the ones it doesn't, I don't find anything unusual. No checksum 
or length errors, for example. And comparing them to the one generated 
by socat doesn't reveal any obvious significant difference, either.
