  abstract= "Sometimes it is useful to be able to invisibly splice a
     process into a channel, allowing it to observe (log or
     present to a GUI) communications on the channel without
     breaking the synchronous communication semantics.
     occam-\π's extended rendezvous when reading from a
     channel made this possible; the invisible process could
     keep the writer waiting until the real reader had accepted
     the forwarded communication. This breaks down when it is
     possible to have choice on outputs (also known as output
     guards). An extended rendezvous for writing to a channel
     fixes this aspect but in turn does not support choice on the
     input. It becomes impossible to keep your process invisible
     in all circumstances. This talk explains the problem, and
     proposes a radical new feature that would solve it."
