My mistake. It's even worse than that.

The Lua code does handle output congestion by refusing to accept any new 
command until the output of the last one is sent. That would be very fine if 
there were no notifications: it won't actually jam the other clients. But it's 
all but impossible to add notifications in such system.

And indeed, not only it does not support position events, it does not even 
send the status updates, which are supposed to be always on.
