Spam in time

Regarding this paper on spamming botnets again: there was a section on detecting future spam, yet in the final discussion, extension of AutoRE to real-time detection is left for future work. I think that the real value of this algorithm will be seen in how well it does on live, new data. The initial results are promising, so why not wait for the next conference and present on results of real-time detection? It could be that there are some political/financial reasons for the paper being presented as it was, but it does feel like we don't quite get to see the exciting conclusion.
