How is that conceptually different from IPC? The graphics system appears to somehow pass mouse and keyboard events to the client programs over a channel. At least that part seems similar to an Unix X11 setup where this would be done over a socket.
I guess I just don't see what is conceptually the difference here versus something like doing basic HTTP over a TCP socket, it seems like the same kind of multiplexing. Either way, you still have to deal with the same issues: can't pass pointers directly, need to implement byte swapping, need another serialization library if you want the format to be JSON/XML or if you want a schema, etc... So in cases where that stuff isn't important, channels would come in handy, but of course that is now getting closer to a local Unix IPC. Am I getting this right?
