Sure, the code we wrote may not work anymore (it was only proof of concept, 
anyway), but the concepts still do. There are programs out there that bypass CCA 
4.x.x.
It is fundamentally impossible to reliably detect the OS of a remote computer, 
unless that remote computer is trusted. *That's* the main issue, and that's 
something that CCA or similar products can not get around.
