I was able to do this using the Node project, i.e. listening on a private/localhost .255 address:

However running it on the broadcast address of a local network segment, even if running as admin, will not work.

You may be able to accomplish this using IPEndPoint and UdpClient directly, though: https://stackoverflow.com/questions/746519/udpclient-receive-on-broadcast-address

If you want to submit a PR with this capability I'd happily take it :)

Cheers, Joel
