Why? Because you can arbitrage to make more than 500% profit? 
i naturally assumed coinlab had blown up mt.gox and all was lost -- i'm way, way overexposed in btc; don't want to have to hit those mean streets again

Payment has never been a problem, you have no idea how Bitcoin-friendly Alipay(every Chinese network user uses it) is, compares to Paypal, at least until now.
Think of BTCChina as another BTC-e, no public relation and never felt the need to do it.
the question was raised before -- is alipay reversable like paypal? i know EVERYONE uses it, however, i never have (always wanted to try out taobao)
