+Often the difference between a working network environment and a well appreciated one can

+network operations.

+There are a number of possible remote desktop management solutions that range from free

+ Answer provided: Check out the new offer from NoMachine, "NX" software:
+ <ulink url="http://www.nomachine.com/">http://www.nomachine.com/</ulink>.
+ </para>
+
+ <para>
+ It implements a very easy-to-use interface to the remote X protocol as
+ well as incorporating VNC/RFB and rdesktop/RDP into it, but at a speed
+ performance much better than anything you may have ever seen...
+ </para>
+
+ <para>
+ Remote X is not new at all -- but what they did achieve successfully is
+ a new way of compression and caching technologies which makes the thing
+ fast enough to run even over slow modem/ISDN connections.
+ </para>
+
+ <para>
+ I could test drive their (public) RedHat machine in Italy, over a loaded
+ internet connection, with enabled thumbnail previews in KDE konqueror
+ which popped up immediately on "mouse-over". From inside that (remote X)
+ session I started a rdesktop session on another, a Windows XP machine.
+ To test the performance, I played Pinball. I am proud to announce here
+ that my score was 631750 points at first try...
+ </para>
+
+ <para>
+ NX performs better on my local LAN than any of the other "pure"
+ connection methods I am using from time to time: TightVNC, rdesktop or
+ remote X. It is even faster than a direct crosslink connection between
+ two nodes.
+ </para>
+
+ <para>
+ I even got sound playing from the remote X app to my local boxes, and
+ had a working "copy'n'paste" from an NX window (running a KDE session
+ in Italy) to my Mozilla mailing agent... These guys are certainly doing
+ something right!
+ </para>
+
+ <para>
+ I recommend to test drive NX to anybody with a only a remote interest
+ in remote computing
+ <ulink url="http://www.nomachine.com/testdrive.php">http://www.nomachine.com/testdrive.php</ulink>.
+ </para>
+
+ <para>
+ Just download the free of charge client software (available for RedHat,
+ SuSE, Debian and Windows) and be up and running within 5 minutes (they
+ need to send you your account data, though, because you are assigned
+ a real Unix account on their testdrive.nomachine.com box...
+ </para>
+
+ <para>
+ They plan to get to the point were you can have NX application servers
+ running as a cluster of nodes, and users simply start an NX session locally,
+ and can select applications to run transparently (apps may even run on
+ another NX node, but pretend to be on the same as used for initial login,
+ because it displays in the same window.... well, you also can run it
+ fullscreen, and after a short time you forget that it is a remote session
+ at all).
+ </para>
+
+ <para>
+ Now the best thing at the end: all the core compression and caching
+ technologies are released under the GPL and available as source code
+ to anybody who wants to build on it! These technologies are working,
+ albeit started from the command line only (and very inconvenient to
+ use in order to get a fully running remote X session up and running....)
