I think you can handle the delay and possibly half duplex.
You probably don't recall the 1950's style long distance calls, where
half duplex was the norm. Cell phones do the same thing. When the
error rate or lost packets start to climb, they revert to half duplex
before giving up and dropping the call. In a cell phone to cell phone
call, the accumulated latency can easily add up to a full second. It's
still full duplex but you still have to tell the other person when
it's time to talk. I have no problem using half duplex or saying
over. However, we will probably need to expose an entire generation
to it before it will be considered acceptable.
Some day, computahs will be powerful enought to anticipate what we
will say next. Then, we can eliminate the latency and half duplex
problem by producing that the caller would be expected to say.
