For things like output level meters, using output control ports ought to be a 
good fit -- we just need to make hosts support them!  The obvious limitation 
is that updates could only happen once per process cycle -- I imagine for 
most such applications that would be fine.

For higher-volume data it's unlikely that any mechanism that fit within the 
existing DSSI host-UI communication scheme would be appropriate, since it has 
no provision for bulk data.  That's probably a case where I'd expect a 
standalone JACK application to be a better approach.

It is technically possible to have a GUI managed by the plugin itself: the 
dssi-vst bridge plugin does that, using a stub OSC manager "GUI" process to 
pass changes between the plugin and host as if they came from a true DSSI 
GUI.  Any such scheme will necessarily be a complex hack.
