VNC is pretty handy for such things though you may need to set up VPN and SSH to do it securely from the internet (read the tutorials).  It also has the benefit of being cross platform and the [dis-]advantage (depending on who you ask) of being primarily GUI based.  There are several flavors of VNC:

  http://www.tightvnc.com/
  http://www.uvnc.com/

At SLUG, we mostly use TightVNC but we are also using it within a LAN most of the time.  BTW, it is really handy for doing classes and meetings where people can look at there own screens to see what the instructor/lecturer is doing.

If console access, SSH.
For GUI:
It used to be FreeNX, but the project seems to have not been updated in a long time.  So far, it looks like the replacment is neatx which is similar...using same protocols/compression (I believe).
The NX protocol is nice/fast, and secure (uses SSH)...
https://code.google.com/p/neatx/

Kind of related to the topic is a 'remote session manager' ...Currently use PAC (Perl Auto Connector) Manager.  It lets you save your preferences/settings for various sessions (ssh,rdp,etc).
It's like vRD on Windows.
