looks about right.

no, the HUP causes the xml config to be re-read and sets some triggers
in various parts for rechecking, but doesn't affecting existing streams,
unless it's a relay that has been removed.

The use of curl/wget or similar can help there, that isn't a big issue
eg curl http://admin:hackme@host:8000/admin/.......?..&...&', the
problem with modifying the file yourself is a question of locking so
that multiple updates don't occur at the same time.

I haven't done the documentation for auth url yet but I've listed the
auth options at the top of the auth_url.c file, essentially

for source stream connection
            <option name="start"    value="http://mysite.com/stream-start.php"/>
            <option name="end"      value="http://mysite.com/stream-end.php"/>

for connecting user
            <option name="add"      value="http://mysite.com/add-ok.php"/>

for disconnecting user
            <option name="remove"   value="http://mysite.com/remove-user.php"/>

header returned if user is authenticated. default is "icecast-auth-user: 1"
            <option name="header"   value="HTTP/1.1 200 OK"/>
