I'm looking forward to that as well.  Did you sort it out since you sent
that mail?

The way it works is that when we set 'name resolve order = file....'
then we use the fake DNS file.  

BTW, for my multi-domain work I need the fake nss stuff working, because
I need a way for Heimdal to use 'dns' to look up SRV records inside make
test, so that I can assist the parent and child domains to find each
