Exactly, that's the idea.

Yes, iemnet comes with [tcpclient] and [udpclient], which accept and
output bytes. They're pretty raw and probably close to your idea of a
[sock] object. However, they don't output all properties of the current
socket.

What I wish to be able to do is done in python like this:

#!/usr/bin/python
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.connect(("8.8.8.8", 53))
print(s.getsockname()[0])
s.close()

All networking objects, including the ones from vanilla, are able to
deal with bytes represented as numbers. I think that's far more
versatile in Pd to use than hex.

I think we're pretty well served with what we have already. What use
cases do you have in mind that aren't covered yet?
