Neither WiFi nor DAB receivers can become as cheap as FM receivers until they are within the same ballpark as far as manufacturing is concerned.
Of course, they are also not the same thing: both WiFi and DAB could be adapted for 2 way communications, thus enabling seamless feedback loops. But we are not talking about sophisticated improvements: we are talking about getting the basic services off the ground. If they work, and if the audience size (presently said to be 140 households) grows, perhaps something else can be budgeted, and at that time, the experiences gained from the basic low-cost solution will come in handy, even if the low-cost solution itself is scrapped.
