this thread looks like a marketing thing to me.
especially as not once anyone mentioned mycelium wallets local trader function, which is well, just like localbitcoins. trade btc for cash, and yes it doesnt charge any fees at all.

(there is no escrow service included) - so only trade with people who you know or at least keep the volume low at first time meetings.
apart from that - this is what you want if you really were looking for an alternative.
