No. Web pages are delivered via TCP, not UDP. In fact, TCP to a broadcast address doesn't even make sense, regardless of web pages.

The thing is that the lack of the -b option in the netcat you're using is a bug. Or at least a missing feature. I'd say bug.

Lemme see if I can compile it up for you. Here you go. No idea if it'll work or not. I've attached just the binary, compressed with gzip.
