entdoc, I think what has been said many times on this board about PPHM Bavi knowledge getting spread and brought under the attention of the larger part of the industry is currently in the process of happening.
The many posts with links to civil, military research links involving PS and PS targeting prove that. More and more other parties then PPHM themselves are writing about it, which implies they have looked into it.
This is the point we had to reach. This is why ASCO 2013 was so important and why the statements of the ASCO Science counsel are what they are. We also saw that some of the research by others clearly dates from before 2012, so some parties are busy with PS since a while.
