Window, Windows, Linux, client and server...

[nelson -]

hi all!
  i'm trying to implement an appllication with this two requirements.
I have a server and some clients. I want to be able to launch an
application (openoffice impress, for example) and display what i'm
doing on the server on the client. Conversely, I want to be able to
have a picture of the desktop client. Is it a thing that i can do in
python? any advice? I googled but i can't find something too useful...
 II know i can use vnc, but i want a pure python solution... if it's
possibile... Doing it using VNC it seems not so "clear"... :)

thanks,
  nelson
