Yes they might be interested, but from a user point of view. They might tell
us some interesting features to be implemented.

Usualy RTLinux and RTAI (https://www.rtai.org/) are used to build embedded
linux devices that work in real-time. RTAI has a lot more features and supports
more devices.
Here is a link with a comparison of them:
http://rtportal.upv.es/comparative/rtl_vs_rtai.html

I don't think that in this stage we should delve into RTLinux or RTAI.
They are used for embedded devices that are used the field devices and
controllers.

Maybe we can use them in the future as RTUs that will some light
version of QScada, drivers for field devices, some small db (because
of the limited resources) and a web server.


I'm currently working on a document that defines the procecess
(reading/writing data, stroing data, reporting, udpating the visual
picture) that are part of QScada. I hope
I'll finish it by the end of next week.

I agree with you completely. It is crucial to share the ideas.
