Putting two and two together...
The new PAW iteration, PAW Classic at last seems to offer the promise of cost effective collision avoidance to Garmin users and those that do not want to use a subscription based GPS Nav program. Although I have yet to witness the audio traffic alerting facility I imagine it will allow this subset of pilots to have as full an awareness of traffic in their locality as other PAW users, whilst also transmitting their position etc for the benefit of others. Sure, they won't get a visual representation of traffic on their Garmin map screen but this is now, hopefully, of no great consequence. (It is of course still possible to display this data on a portable device using say, "XC Soar", which is free, as discussed in Ian Fallon's Software Installation Guide).
This audio alerting facility is potentially "hugely important" as it will allow a large section of pilots using Garmin devices to join in the PAW revolution to SEE and BE SEEN.
NB. The above comments are on the assumption that the audio alerts are available from the RPi 2B audio output connector.
