I relaize this is a very old thread, but I haven't been able to get RAP for
several months on my news server and it finally recognized it's still out
there.

There was a recent news blurb (Early December) that they figure it may be as
long as 10 years before the so called locator service is in wide spread use
with the high accuracy originally claimed..

As I understand it supposedly works with a combination of GPS in the hand
held with the tower applying the correction features.
