minor point, it's HTTP POST

correct.

Hmm, not sure in xml provides an include option and whether libxml2 will 
handle it, it's not something I've looked into, but if it does then HUP 
should work, and for 2.3.1, the new auth should apply for new listeners.

There is another possibility which might be easier. In the -kh branch, 
where I have an updated auth engine, you can specify an option 
"stream_auth" with a uri that works in a similar way to the others. It's 
triggered when a source client tries to auth or when say metadata is 
updated on that stream.  I haven't had much feedback on this but it 
seems to be working well enough.
