I have a device that does that, the Sharp Zaurus. From what I
understand, a microphone has a different impedence than a headphone
speaker, so the hardware switches the one earpiece betwean mic and
audio out based on that. Only problem is that it plays havoc with
certain audio out devices, such as a cassette adapter (not enough
impedence), so I'd rather have this software controlled (i.e., switch
one or both lines to audio in depending on the app that has controll
of the connecter).
I also had a computer motherboard that would do the same however
software configured. It had the ability to produce 5.1 sound however
if you wanted to use a microphone you had to reduce that to 2.1 sound
and use one of the output jacks as the microphone input.
