Just Launched: You can now import projects and releases from Google Code onto SourceForge
We are excited to release new functionality to enable a 1-click import from Google Code onto the Allura platform on SourceForge. You can import tickets, wikis, source, releases, and more with a few simple steps. Read More

The comments there seem to suggest that this is related to remote
hosts, but what I see in man (wandering through ip(7), bind(2),
packet(7), socket) leads me to believe, as I thought before, that it's
the local address.
This also says, if I read it correctly, that there's nothing between
0.0.0.0 and a single address, i.e., no /24's.
So what I'd like is an optional IP address. My understanding is that
on a machine with multiple IP addresses you can listen on one or on
all. Sometimes you want one and sometimes the other.
So far I don't see how to do that with the optional socket argument,
since that could only have been created the same way, giving an IP
address of 0.0.0.0, right?

This seems to suggest (again) that the address is the remote IP.
I think it's the address of the LOCAL machine.
If I have two IP addresses I want to use ONE of them for this socket
so I can still use the other for another one on the same port, for
instance if I want to run two different web servers with my two
different IP addresses.

The man pages suggest 0.0.0.0 is not a mask but a special case
