Assuming the FAA is reasonable is a big assumption, but if we are stuck with remote id, what is a reasonable solution that we could live with? If we assume we could register a transponder that was portable between planes (rather than a per-plane registration), and it could send out a timestamp, id, latitude, longitude and altitude (and possibly another message with take-off location); this could actually be a helpful device for finding lost planes.
I was thinking of combining a Raspberry Pi (A) computer with a RFM69HCW transceiver (915 Mhz) and a small GPS. With the right antenna this could broadcast several miles (or from space if pushed). It could also run off of a servo lead.
At retail prices, this could be built for $35 in parts, if manufactured the price could likely be half this price (as well as half the weight). I could live with this.
I still like the idea of LAANC for most line-of-site and fixed site flying (no transponder needed), but think a simple transponder like this is something we could not only live with for FPV, but would actually have some benefit. Similar hardware (without the GPS) could plug into a phone as a receiver to show where the plane was located.
