So your private agreement, in addition to specifying the meaning of your PUA characters and probably some sample glyphs, can also specify their properties, overriding the default properties.
I don't know if you can even do this. My understanding of the rendering process is very sketchy, but I seem to recall that things like directionality cannot be specified by a font or other easily transmissible piece of information, but has to be baked into the application or rendering engine itself. This severely limits the utility of the PUA, if applications that use it have to be written from scratch each time. At least with stuff that is font-dependent, you can use ordinary word-processors that honor OpenType or Graphite or whatever.
