What does HackerNews think of netevent?
Input-Event device cloning utility. Use it together with ssh/netcat/... to share input devices among different machines.
The core architecture is to ssh in to the machine, and forward Linux /dev/input* events to a python app that re-emits websocket events.
This makes me think a little bit of netevent[1], which is a small utility for forwarding/cloning input events (by creating a virtual uhid device that re-creates an input stream), usually used with ssh to forward between machines. It would allow for the remarkable to act as just another generic input for a presentation laptop, for example. One might be able to then use Gromit-MPX[2] or DrawOnYourScreen to turn that forwarded input into on-screen drawing.
Todo: figure out if either of these apps can listen to a dedicated input device & ignore others, such that one can present as usual, but draw atop with the tablet.
In general, there are just so so so many open issues & pull requests open. It's great software but wow, there's so many different environment's it needs to work across, & trying to maintain this project seems like a nightmare.
Not cross platform afaik but I really dig the netevent[2] project linked in this thread, which is a lower-level network input forwarder.
Last but not least, Barrier was discussed on HN with 14-comments a year ago[4].

For (integrated) mouse support you could take a look at a project from a good friend and colleague: https://github.com/Blub/netevent
Allows passing along arbitrary input events over the network and more.
