>> I can not stress enough how important this JCS work is.  Anders talks about the banking industry using this.  But In addition to the banking sector, the entire international cyber threat intelligence community will be using JCS, which includes hundreds of major and small vendors, nearly every industry vertical, and many governments around the globe.

Anders has done amazing and brilliant work here.  Is it going to cover ever corner case? Probably not.  But honestly it does not need to.  It just needs to solve the problems people need, and it does.
