Hi all, 

Thanks for the very enlightning mail Rene.  Also, Yuriy wrote

An interresting thing to follow in this respect is the Berlin project
[1].  The claim is, that due to thier advanced server-client protocol,
remote displays should work much better than for X11.  Now, that said, 
Berlin is still in a alpha phase (not ready for production).  I
haven't tried it myself yet, but will one of these days (there exists
.deb packages for Debian GNU/Linux in "testing" [2] - try it Brett).  

Also, it seems that we have indeed come full circle with all the
different apporaches to the Graphics abstraction layer in ROOT - First
there was a suggest that we had TGQt, TGGtk-- (or something), and so
on deriving from TVirtualX, then it seemed that was a bad idea, there
was a suggestion off doing TQtGuiFactory, TGtk--GuiFactory, and so on,
deriving from TGuiFactory, and now  Yuriy and Brett (180 turn :-) is
talking about TGQt, TGGtk--, etc.. Very intresting development.   

To those of you not in the thread but thougt it an intresting subject,
thanks for your support.  The funny thing was, that the debate was
actually taken off-list after [3], but then it seemed that there was
enough intrest to put it on-list again.  

With the danger of being flamed by various people, I would suggest
that ROOT's mailing lists got split up a bit more:  

  rootuser:  User questions, like "how do I turn every third axis-tick
             blue?" (LOL Goerge), and so on. 
  roottalk:  Debates on various things, like the current GUI debate. 
  root-bugs: Open this list so that users can subscribe to this list,
	     which will hopefully help the bugfixing - Bazaar style
	     development [4]. 

Personally, I'd probably subscribe to all three, but users that do not
care about technical details, as "how to make a GUI threadsafe under
operating system ObscureOS", "should VMS make a comeback in terms of
ladida" and similar <grin>nerdish</grin> things, could just subscribe
to rootuser. Just a suggestion. 

Yours,
