That, combined with the Overstock news (which I'm guessing is coming from Patrick on the 6th), makes me confident that Counterparty will not be overlooked as a possible solution if Counterparty is in line with what they're looking for.
That is something I am assuming based off of information that is available in the public domain. I could be wrong.

The topic of Patrick's keynote is: The blockchain has proved very well suited to the exchange of digital currency. But what about exchanging shares of public companies? Overstock.com CEO Patrick M. Byrne, a longtime critic of Wall Street, is actively pursuing a model for trading stock on a peer to peer basis *using the Bitcoin protocol*. In his talk, Byrne will discuss the challenges and opportunities presented by a decentralized stock exchange.
It says he's looking to use the Bitcoin protocol. The only 2.0 platform that is *built on bitcoin* and has publicly stated they've spoken to Overstock is Counterparty. If Mastercoin or Colored Coins were speaking with Overstock I think we would have heard something about it by now.
I think Bitshares tried a dialogue with them. Don't have the details, maybe someone can fill in.
