Had look and does have prices on website: http://www.limemicro.com/buy_now.php
$110 per chip for one at joe blogs consumer price, so good indication upon bulk price, let alone trade.
I do somehow wonder how long it will be to reuire some sort of radio license just to purchase such items. I recall how in the UK you needed to know and pass a test in morse code to legaly use a HAM radio, not the case now.
It will take some time but i am sure it is going to big business in the future.
