My suggestion, since you're familiar with ssh already, would be to use something that is more or less considered to be "built-in" with X and ssh.
It's called X11 Forwarding and here's a link on how to get it working:
X11 Forwarding using SSH
If you're not interested in that, you can pick up vncserver and vncviewer for most distros. There's also a package called rdesktop that will provide you with multiple remote desktop options.
As far as hardware detection/identification, if you're looking for a GUI tool, you can grab Hardware Browser the package name is "hwbrowser" and you should be able to grab it and any/all dependancies using Yum.
For future reference, please add the distro(s) that you are using to your profile, or at least include that as part of your questions. You'll get more accurate responses that way.
p.s. I have also never heard of Everest Lavalys software.
