Just a quick note on progress:
I added a metric display option for the local display, so that the folks in Canada and Europe have an easier time. Also added a Density Altitude readout, handy for aviation related use.
On the firmware side I added the option to upload to CWOP, WX-Bug and PWSweather/WeatherForYou in additiotion to WeatherUnderground. The upload protocols are complete and working, I just need to add a couple more fields to the station GUI for ease of configuration.
On the HW side I switched to the phone/FAX style cable for the Air-data sensor modules. This makes it easier to move the sensor away from the main station controller. The FAX cables are available at Fry's and on E-bay for cheap, I have a couple of default lengths available as well.
And on the Air-data module I introduced a new Silicon Labs hygrometer chip that has a better filter than the Honeywell part.
