Would the application work with a hosts entry like this?

127.0.0.1    hostname.dummy   localhost localhost.localdomain

(Make sure you pick .dummy so as not to interfere with any other DNS.)

In theory you could leave off .dummy, but then you risk hostname being
completed with the search domain in resolv.conf, which creates the
problems already mentioned with putting hostname.domain.com in
/etc/hosts.  (I have not tested this at all!)
