Python X2Go is only needed on X2Go Clients. Or if you want from one  
X2Go session to the next (that is: running pyhoca-gui in an X2Go  
Session).

I guess that the RPM archives need updating. We currently have quite  
an issue with latest libcairo libraries (1.12.x). The let latest  
builds of NX crash. The issue is partially fixed in x2goagent/nxagent  
3.5.0.13, but that one is not packaged as RPM AFAIK.

However, NX redistributed v3.5.0.13/.14 (.14 ist latest version out)  
are not fully functional again either. There are two issues currently  
known:

   o GTK apps (based on libcairo) behave very sluggishly
   o session resumption does not work optimally (text glyphs are missing)

For GNOME3 (gnome-fallback in case of X2Go) you also need our latest  
X2Go server code (not yet released). I will discuss a release date  
with Alex.

Yes. That is possible.

I do not use Cent OS, but the above diagnostics I have met during  
development on Debian and Ubuntu systems, as well.

Greetings,
