The key for wide spread adoption would be enabling more than point to point communication, and figuring out how to make the hardware really easy to make or obtain. Are there any known algorithms that can scale mesh nets to high throughput? And, how are we encouraged to run intermediary nodes? I'd set myself up with this in a heartbeat, if it let me communicate with people 300-600 miles away and was easy to set up. Also, is encryption allowed?
