Steffen You have done some amazing work and we now know what we are dealing with rather than just guessing as we've done before.
I think its not about the last 20 years but about the next 20. I think we will see an increasing number of ethercat capable devices in use as more vendors adopt the technology. There are also an increasing number of linuxcnc users using the software on commercial projects and retrofits of commercial machines. ROS appear to be simply embedding the SOEM in a sub folder in their ethercat master wrapper based on an article they link to in the readme. I guess they can do this under the GPL. Any restrictions appear to be placed on users of the technology, not the software developer. Linuxcnc does not use software, our members do. This is an important distinction. I think this allows Linuxcnc to treat the proposed driver as being GPL'd at a distribution level like ROS has. Now we know of the SOEM's existence, it would be preferable to use it over the IgH ethercat master if it's compatible with our architecture. It's a much tighter integration then. It's clear that membership is not required. I can't see any impediment to building a separate repository like has been done with mesaflash that embeds the SOEM like ROS has done. If the rules change, it will be simple to excise the orphaned child or just remove the SOEM subfolder.
