Hi Tom,
 I would certainly be interested. I have 4  receivers that I would like to add that feature to. I was thinking of also trying the technique with other receivers, such as Trimble Jupiter/SMT or newer Ublox which provide quantization data so I was thinking of a more generic serial/PPS pass through which could handle all those protocols quantization messages.
