First, thanks for the detailed response. I'll add it to my notes for the 
next attempt. And on seeing your posted example, it does ring a bell... 
Sorry if I did miss it - or forget I saw it posted.

Re: dbus, pipes. Your guessing my aims correctly.

There are crude ways to call povray in a loop today - adjusting say 
spline control points. Such an approach which would be made much cleaner 
with some sort of window id / into functionality as you've suggested. 
Such an approach if, working with Tk frame widows, opens up Python and 
Tcl as the scripting mechanism for "modeling/simple POV-Ray created 
widget windows."

However, I'd like something a step beyond this coupled with rtr - which 
in my minds eye at the moment - requires a couple of os level tasks be 
talking to each other(1) continuously - or to, perhaps, be aware of X11 
events in a shared way.

I'm ignorant of too much at the moment to know what I really want.

There are all the widget packages too - Qt, etc. With povr, I'm aiming 
at more of a small utility niche with little or no overhead - something 
'easy'. Pipe dream I expect, but a push here and a push there and maybe 
some path to such a thing opens up....

(1) - POV-Ray has Thorsten's povms which has some facilities for such 
communication. While I've learned tiny bit about that code of late, I'm 
a long, long way from being able to swing that code around as a useful 
hammer inside POV-Ray - let alone extend it.
