William,
You got the architecture right. The point is not having to render images
and treat UI events, thus having all processing power for mathematical
computation. X Windows System and Wayland are memory and CPU hogs and in
some cases those resources are at a premium...
As I read the code, trying to figure out how WSTJ-X works, I notice how
tightly coupled UI and data processing are. I understand it can be easier
to show things on the GUI, but decoupling those could allow for some
different UX (text-only, for example) or, as I suggested, some "smart"
remoting.
To be 100% honest, the distributed processing approach I proposed is just a
thought experiment on how to decouple the many modules. Having each
"module" on a different machine is usually how I think when I try to
decouple complex stuff.
I'll keep studying the code to try and figure out how it would be
possible...
