I'm a little confused of what the current state of the project is.

The Photo Gallery [1] features a couple of installations, running on 4k screen hardware and a Xeon X5690 as it seems, but is still based on CentOS from 2004 and running a Linux 4.18 kernel?

Do they have compilation problems or kernel mod problems, or that they need to port their display server and kernel mods to newer APIs in the upstream kernel?

Looking at the roadmap [2] this looks like a major development effort with huge stories along the way. Is there a foundation people can support financially?

The project seems to be sleeping. The development was veeery slow. It was not open source so, in the end, CDE is the way to go if you need something like this.
