Yes. The fundamental overriding theme that hits me as I think back upon the overall bird's eye view of it is that there appear to be considerable efforts expended to make things not easily reviewable as far as Internet history goes and transaction history and data: where it goes, where it gets compiled, aggregated, and attributing the sources to everything. There seems to be a common theme of bringing lots of little things together and then letting them fall apart in a way that is not easily auditable. That could be done for security purposes. That could be done for obfuscation purposes. It makes me very suspicious, however.
For example, there is an underlying theme in the Ephemeral project—the name “ephemeral” sort of gives you an idea—and it utilizes channels and web sockets in ways that can communicate very covertly. That's not to say that it's necessarily something that is malicious on its face, but it is done in such a way that it's considerably difficult to prove beyond any doubt that a certain transaction has taken place in regular forensic means.
