Hello all, I'd like to provide a short follow-up on this matter, as at this point I have some more information and a clearer path in mind how to achieve some of the things I've alluded initially with respect to using PipeWire as a replacement for Waltham. While PipeWire is similar to the remoting plug-in, such that in combination with a helper client can stream out data buffers over some kind of a network, piggyback on it to deliver input events from one side to another isn't really feasible to do. There are far better solutions and these are either RDP or VNC. It remains to be seen which of these are more suitable here - it depends on the encoding/decoding technologies they actually use. So, with that in mind I've renamed SPEC-4689 and updated it with some of the things I need to piece together to get this working. The support for achieving this is WIP in upstream, at this moment, libweston supporting both RDP and VNC but not in this particular use-case (combination) that we have here: streaming data buffers on a remote site but also display something natively/locally. Further more, a Wayland native client using freerdp2 or anyvnc would needs to be on the remote site to display the incoming data buffers, process inputs and send them back. While there are such clients I don't know at this moment how much of these we can use or re-use. PipeWire is still the technology to use in screen sharing the entire output or just a window app, just not as a replacement for the use-case we have/had with Waltham. We would still like to advance our PipeWire usage in AGL so I've created SPEC-4711 for just sharing/screen sharing functionality using PipeWire. Additionally, I'd like to point another useful feature which was brought in by Scott Murray, and I think it would be good to have on the feature planning list alongside with the Waltham replacement task and PipeWire. It's about the compositor being capable of using a *.d directory, drop-in configuration files, similar to systemd or apache conf.d files. I've further added some examples in the associated Jira task SPEC-4710. Thanks!
