Ads-b and sailplanes

Has anyone been following the latest moves from the FAA on ads-b and experimental aircraft? A recent article in flying suggested that they are going to relax the requirements for experimental planes so they need a GPS source that is equivalent in performance to TSO'd units.

If this is true, it might relax the requirements for those with Trig TT22 transponders so that they can use cheaper GPS sources like the GRT GPS-EXT-RAIM unit that they sell for just under $500.

I've decided that it's cheap enough to give a try, so I just ordered one and will be playing with it over the next few months. It certainly beats forking out $3000 on the TSO'd unit sold by Trig.

If anyone has opinions, experience or also intends playing with this I'd love to hear. I fly out of Harris hill which is right by a big iron airfield and it'd be nice to see them on a screen before bumping into them. I also like the idea of a couple of us flying with ads-b out so that people around us get to see the in portion. S emus like even a relatively small percentage of us on the new standard could help safety given the idiot decision by the FAA to restrict access to the "in" data to a hockey puck around each plane with "out".
