<sigh>, the steps 1 and 2 *you* mentioned above, are not about dbus activation,
if we do dbus-activation, we don't need to check if the file-manager is running
at all, but we can NOT do dbus activation, since that does not allow selecting
which file manager is the users preferred one.

So dbus-activation is not an option. Unless we give each file manager a
unique service name, which does not seem like a good idea to me...

And how do we deal with multiple apps (ie nautilus and konqueror) offering the
same dbus service name? AFAIK dbus currently does not deal with this.
