I appreciate the contributions you've made to the shaman community here. But this should have been a PM.
(To answer your question, Stassart mentioned in the resto cataclysm thread that he's considering implementing shaman_hep as an in-game addon instead of an external parsing tool. Feel free to offer him support, encouragement, beer, or whatever -- in a PM.)
I am curious to see the new shaman_hep. Are you rewriting for the changes?
