Yeah, I did.

I think he might have meant that he's building them using stereo jacks, but
they will only deliver mono sound (since the Newton only puts out mono)

I've had almost all of the parts for such a project for a long time now --
the only thing I'm missing is the LTC1323 serial line driver (but they can
either be ordered from Digikey or replaced with a MAX232 or a MAX3232). I
also have sketches of a design I talked about with Eric Schneck (NewtJabber
/ Siemens PocketReader driver guy) a while ago.

(That reminds me, I made a motorized Newton stand out of LEGO and haven't
posted the pictures yet!)
