I'm currently in contact with one exchange operator; although Havelock is on the list of possibilities, it's not first on the list. It has a way to go yet in terms of bulking up its relatively low volume, low liquidity/wide spreads, and the absence of derivatives. However, if any exchanges make a public announcement about plans to support ex-BTC-TC assets, or contact me directly, then I'll be very happy to explore in more detail.
