mk47at: It looks like the Galaxy telemetry stuff (function signatures in the output of nm -Ca) finally landed on Linux. I haven't used wireshark to confirm it, yet. It's interesting that they make heavy use of Boost.
Feels kinda absurd to +1 this post, but thanks for the information. Does, once again, show why I'm glad there isn't Galaxy for Linux yet. This kinda crap will be much worse then, and once it's available for all platforms, it will be easier for GOG to drop the half-hearted promise of "it's optional".
See there is another update out - some bug fixes and other small changes. Will presumably take a good while before we casteless penguins get it, but I'm glad to see the developer pushing out bugfixes that quickly.
