If someone really misses functionality, we should fix that deficiency in hw/xfree86, xf86-video-dummy, or xf86-video-nested.  Also, there's nothing stopping anyone from using older server versions if they still need these DDXs.

Thanks for examples, I though a good job , is replace 
/usr/bin/Xvfb
/usr/bin/xvfb-run
transparently .


Other subject is vnc any replacement for x11vnc and x2vnc, I am worried
about applications which use code of X11 like this two: 

x11vnc-0.9.13-1.fc16.x86_64 

rpm -qi x2vnc-1.7.2-12.fc15.x86_64
Name        : x2vnc
License     : GPLv2+
URL         : http://fredrik.hubbe.net/x2vnc.html
Summary     : Dual screen hack for VNC
Description :
This program will let you use two screens on two different computers
as if they were connected to the same computer even if
one computer runs Windows.


Thanks,
