I actually thought the documentation was pretty impressive for a proof-of-concept release.
Anyway, I gave it a try.. I got 0.9BTC from testnet faucet.. I burned 0.2BTC which gave me 0.2 swapbill.. then I tried a offer_buy qty of 0.2..
Now I have 0 balance of swapbill and zero balance of BTC.. lol.. dunno what happened but the coins *poof* gone

I think it needs a nice friendly GUI to really hold peoples hand through the process to get people involved.. but that wont guarantee success either.
I'm still skeptical that burning host currency will mean it keeps a stable value.. If I write the serial number of a 20 dollar note on a piece of paper and tear up the $20.. the paper with a serial number is not really gonna be accepted as $20 or even anything at all..
Edit: It appears I just needed to wait for a block or two for my testnet BTC change to confirm, now my BTC is back.. the 0.2 swapbill is probably committed in a pending tx i suppose.
