Yeah, I had noticed that it only appeared to be halfway delisted - trading halted, but listing not altogether removed; I was wondering about that.

Although, IMHO, BitShares would probably benefit much more from centralized exchange listings along the lines of bitUSD:USD, rather than BTS:BTC or even bitCNY:BTC. Smartcoins paired with fiat would be much easier to run market makers on, and demand for counterparty-risk free price stable assets would drive demand for BTS more aggressively than direct demand for BTS.
