Just read some material on this Satellite tracking system and it's potential for use in lieu of VFR, Family, Friend and GOKALL. The system has found many fans in high density traffic areas and for flying off to a frozen lake beyond wherever. It is another thing to buy, of course, but the tariff is ~ $100/yr. One hamburger trip might be worth it ? I'm wondering how many EAA pilots are using this and their experience with it.
