Finally. After like a 100 searches I found a page..
http://radscan.com/nas.html
and a pitiful support list
http://sourceforge.net/p/nas/discussion/705744/
a woefully underpopulated wiki
http://sourceforge.net/apps/mediawik...itle=NAS_Links
and a very hard to parse mailing list
http://radscan.com/pipermail/nas/
what joy.
will dig
