I think that politically this is a awful time for that.

Bitcoin is still largely unregulated, and this allow for all sorts of innovation, yet the media is already scaremongering around because it is "anonymous" and used for laundering and drug dealing.

If Zerocoin attracts true media attention, then you will get a political firestorm of people claiming that someone is making Bitcoin even worse for nefarious purposes. And of course, the paper mention of drug deal does not help with that.
