Not really, I'm afraid.

We all know a hubbed_hosts file works. Mark Fletcher has written
extensively about it and I have said a thing or too also. What I want to
know is why following the advice from Liam O'Toole doesn't work for me,
even though I have followed the instructions exactly.

BTW: It would be 'desktop: 192.168.7.20' and 'desktop.monet:192.168.7.20'
in hubbed_hosts.
