I prefer EAP TLV method.

I was wondering whether this question should be debated in EMU as well since the question is less
about NEA and more about how to use EAP as a carrier for NEA. EAP-TNC creates an EAP method to  
carry application data (posture is pretty much an opaque data exchange for EAP)  and creates a precedent 
for other EAP methods to defined to carry arbitrary data sets. I would presume the EMU folks might want to
say something about that.

 kaushik
