Can you guide me (or someone else surfacing) towards what would be
required to have LinuxCNC readily compatible with that external
EtherCAT package on Debian?
Personally I know nothing about EtherCAT. I have always been a
little
afraid of the licensing complexities mentioned here:
https://etherlab.org/en/ethercat/
Etherlab itself is GPLv2, but _using_ it seems to bring a different
licensing restriction into play. And I don't know enough about
licensing to know if that's a problem.
I followed this link, and couldn't find an obvious link to the
licensing docs. Am I going blind? Or are they acting like a
submarine, ala the compuserve debacle from about 25 years back?
It is in the "Notice" section below that copyright thingy:
The license above concerns the source code only. Using the EtherCAT
technology and brand is only permitted in compliance with the
industrial property and similar rights ofBeckhoff Automation GmbH
<http://beckhoff.com/>.

Yes, I read that too, Steffen, but failed to find a statement describing
those rights.
They did not put anything there, I agree.
Thats precisely why I mentioned the GIF debacle. I'm a
genuine old fart, my history starts in late 1934, with a good memory
about such dishonest goings on. It took maybe 20 hours for gifs to
disappear from the net, totally and completely then, and maybe a week to
fine tune png and get the first version out the door. Where is compuserve
today? A footnote in history at best, but not remembered with loving
thoughts. We invented the distastefull term "submarine patent" to
describe what happened.
I don't really want to be involved with an entity that references
additional rights, but doesn't make those readily available.
Maybe I didn't look hard enough but I did look with the idea of learning
what those additional rights might cost.
Nothing, so I was assured.
I propose we describe what we want to do and then they either agree and
make LinuxCNC.org a member or they don't.
Best,
Steffen
