Indeed. Network transparency is not to be sneezed at.

Of course, there *is* a well-defined client API to interact with X,
and there is no reason (it seems to me) that API *must* call through
an IPC layer, if it knows that a local connection is being made.
Are there apps that directly speak to the server using X protocol
without going through Xlib? (and if so, for dog's sake *why*?)
