The big problem here is the comunication from the viewer to the plugin.
A pipe is created but is not read by the plugin. For this to be
possible, it would need an event handler associated with the pipe (I do
not know if this is possible) or to create a new thread (I might be
wrong?).

This already exists. It uses (once more) the property bag. I already use the 
mechanism in my programs. The GChem3D bonobo control (from the Gnome Chemistry 
Utils www.nongnu.org/gchemutils) implements such a mechanism for two properties 
(display3d and bgcolor).
It works both with attributes in and <embed> element or with <param>
tags inside an <object>.

The other points are quite interesting but I have no reliable answers by
now.
