Pharmacology - Is Shulgin holding out on us?

[Desertfox]

At one of his talks from burning man Sasha says he has been very careful about not talking about current molecules he is working on because of what happened when 5-MeO-DALT was made before it had really been assayed and he did not know its safety or dosage but within a short time a Chinese supplier had synthesized it in mass quantities and was selling it. This makes SWIM wonder what Sasha has been working on for the last few years but has been keeping quite about as he has to wait to release anything until his new book is released(which he hasn't mentioned in a while either). Have any SWIMmers know of any interesting structures that have possible activity that Shulgin may himself be exploring? SWIMs recent post about salvinorin B ethoxymethyl ether's recent discovery has kindled his interest in possible other substances that were not in Pihkal or Tihkal... If there is a thread discussing this SWIM apoligizes.
