Right, if a system has dbus libs it is likely that if there's a service 
  provider, xfrun4 will also be built with it. Most new distros where 
xfce 4.4 will be provided have dbus as default and as such will build 
terminal, xfmedia and xfrun with dbus. Users who build their own from 
svn can rebuild when they think they want to use dbus. I think this will 
be a category of users who know what they are doing so they can just as 
well bind the key to dbus-send directly.

So I'd rather keep it simpler, as it is now.

Maybe distro packagers can chip in regarding the default config options 
they use for building the xfce suite?
