Probably we have a quite optimized video rendering, but I won't be using that at all, at least not via remote. I am not familiar with Wayland structure; what does it mean? each client has only access to what it personally wrote? I seem to understand some kind of screen-capture (e.g.: for screenshot) is possible. Am I wrong? > wayland. If you're interested the guys from tightVNC have worked on the I already tried contacting them, but they do not seem to have anything ready (at least they didn't answer to a request for a quotation). > subject.

Can I (in Your opinion) use the code in .../weston/clients/screenshoot.c and insert it in a FreeRDP server (or a LibVNC sever)? Another problem (possibly major) is I apparently do *not* have libinput on my target; what are alternatives?

I'll have a look, Thanks for the hint. I assume I will have to write the equivalent of FreeRDP/server/shadow/X11/x11_shadow.c, possibly using the code from screenshot.c, correct?
