No, I was not aware of that. Is it really? On windows, you can broadcast 
UDP packets with a [netsend 1] by sending it a "connect" message with an 
IP broadcast address, such as or x.x.x.255 (where x.x.x 
is the local network address) which are the standard IP addresses that 
are reserved for broadcast.

On linux, you get a "permission denied" message if you do that and it 
does not connect nor send packets. I seem to remember that someone told 
me that in the Linux those addresses had been disabled (don't know why), 
that is, that it had been possible to use them in past versions.

I thought a broadcast address was just an IP address like any other, and 
I thought the operating system's network protocol stack took care of 
broadcasting the packets that are addressed to that address. I didn't 
know there was any need for a "feature" to implement it. That's why I 
called it a bug. The "permission denied" message made me think that the 
reason it didn't work was that Pd wasn't doing all it had to do to get 
the permission to do the broadcasting, or something like that...
