I've never used hesiod, but I'd assume that the passwd data etc would
be kept in a zone used only for that?  The data transfered would not
be too great.... you would only do the transfer on the first call a
process makes to getpwent() and cache it all until the process calls
setpassent().  

As you said, making the host a secondary for the hesiod zones would be
a very good idea.
