1)Xwindows is more like GDI+terminal services. A *NIX box can run more then one xserver (where windows only runs one gui) and it doesn't care if clients connect to said servers locally or across the network

2)See openldap.org -> the quick start guide: http://www.openldap.org/doc/admin/quickstart.html

1) On Windows, a single interface puts application windows on the users screen and decides where they go, how
they are moved, and how the communicate.  On 'nix machines, this is split between two separate applications,
the X-window system, which takes windows from any networked application and displays them, and the window
manager, which moves, arranges, and handles communications for the various application windows.  There are
probably 15 different window managers available for your RH9 machine.  In other words, the window manager is
the Look and Feel part, while X-windows is the underlying hardware.

The cool thing about X-windows is that a user can ssh into a remote machine and start an application, which will
open a window on the local machine, with the actual process running on the remote machine.  This allows users
with slow machines to use graphical programs on supercomputers, for example.

You can use heartbeat/ultra-monkey for building a completely failsafe clusters.
For more information, visit http://www.ultramonkey.org/

If one linux server crashes, the other box takes over the IP address and starts acting up as the main box.
