Support for binary websockets about sshy HOT 3 OPEN

Also, if this were done, it could also mean that SSHy would be able to work with an out-of-the-box wsproxy instead of requiring the patched one supplied with SSHy. That would be a big bonus.

I notice that upstream wsproxy has now pinned the version of ws to 2.x, which means it doesn't need the patch in stuicey/wsProxy@8ef26ac (although it still might be a good idea to submit this upstream so it can move to ws 3.x)

Yeah, its trivial to update this for use with websockify (see here), I'd be hesitant to make it part of the normal release though unless websockify or another major websocket proxy supports multiplexing? If theres a better suited alternative I don't see the harm in switching, all wsproxy does is bridge ws <-> tcp sockets.

wsproxy was developed for use with Ragnarök Online, so I wouldn't be surprised if they want to stay at ws 2.x to maintain compatability.

Is ws (library) >= 3.x required for multiplexing then?

I don't know much about websockets, but as far as I can tell, the benefit from multiplexing is if you have lots of tabs open with ssh sessions, all going to the same backend server. Is that correct?

ISTM that binary websockets would be more widely compatible. You can still release an optimised version of wsproxy, using a newer version of ws library, but it would be optional.

Given that wsproxy is barely maintained it's probably worth forking wsproxy with a different name, so it's available via a simple npm i.
