I've never tried it.  I don't think there are that many people on this 
particular list.  You could try posting this on the NTP questions list.  
I'll bet you get some response.

(PS - If you email me and don't get a quick response, don't be concerned.
I get about 300 emails per day from alternate energy mailing lists and
such.  I don't always see new messages very quickly.  If you need a
reply and have not heard from me in 1 - 2 weeks, send your message again.)
