Sure, I'll bite. I created a CoinPrism wallet and was assigned the address: 1DAXAwYFencj3CXWhcjUg6Fvo3JhjRxrev
So are OwlCoins redeemable for anything real or are they just for experimentation?

I am still interested in the answers to these two questions:
1. Does the open-assets protocol have a formal and publicly-visible method for an issuer to remove the color from a coin?
2. Can colored coins using the open-assets protocol be traded via coinjoin transactions?
Sent it.
1. I think so, when you send it to a new address without the meta tag it becomes uncolored (recycled). I think that's what Coinprism does when it uncolors.
2. Sorry, I don't know.
