Yes, of course. I am not worried about the workstation end. There are
enough options there. (Windows/Xming, Windows/eXceed, Linux, or Mac OS.
Any one is good enough.) I am more concerned about the embedded end.

That's OK. Telnet or SSH to the embedded system is perfectly fine. It will
be done anyway.

This is exactly what I am trying to learn. What is the absolutely minimal
set of tools which I need to embedd in order to cast my graphical display
to a remote screen?

I am glad to hear that nano-X includes some widgets etc. Now I need to
learn where they are and how to use them.
My observation about the Nano-X website is that it seems to focus on
supporting the actual hardware displays. Certainly it is the case on the
Analog Devices KOOP website, where they talk about Nano-X driving LCD
screens (see the next paragraph).
You can see what the Blackfin website is saying: "Before running it on
Blackfin uClinux platform, make sure your linux kernel has video
framebuffer support. In our released uClinux-dist package, there are three
framebuffer device drivers available: adv7171, adv7393 and TFT LCD
LQ035Q7DB03."

The kind of remote app which I need is less than clearly described on
either website.
