Very interesting and starts to make the posibilities of more open baseband software much more viable. Also Software defined radio projects become cheaper.
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.
