Prediction: if this does take off and become a serious problem for the Chinese government, they will approach the CDNs and force them to implement blocking or get filtered. A few may take an ideological stand, but most CDNs will comply, as if they don't, their customers who need to reach China will simply switch to those that do. If they don't care about the Chinese market and refuse, they'll simply get blocked. Of course the more likely scenario is that this simply doesn't catch on in the first place, or not to a significant enough degree that it requires a response.
