The latter approach--just change the master backend "IP address" setting 
by running mythtv-setup on each host *and* update all 
$HOME/.mythtv/config.xml files (if nothing else, take the <USN> tag out 
of <DefaultBackend> so it will find the correct/current one).  (This 
presumes that there's no reason to actually swap the host names of the 2 
machines--and from a MythTV perspective, there's none.)
