Just wanted to follow up. I have it working.

I enabled vnc on my Linux box at home. So now I ssh into it and launch firefox, than Citrix, and it works. I can than RDP through my citrix server to my utility machine at work (a VM on ESX server running essential apps)

The command I ultimately use is:

ssh -C -X -p <my custom port> <username>@<domain.name> vncviewer localhost

This grants me a full on desktop environment via SSH. (Ubuntu for the record)
