As you say in your post, any good firewall/border router would stop this.
You could try a normal http:// url to your apache server with a hacked up
NTLM-authentication module that records the challenge/resonse fields in
the SSP exchange... This would most likely bypass any firewall/proxy...
Never actually done this, but it might be fun to hack up som code similar
to slingerbult[1] that just solicits an SSP challenge/response and returns
a 1-pixel transparent gif or something... ;)
It would be fun if someone tried this out, I don't think I will have the
urge to do it any time soon, but it's been on my mind for quite some time.
