Vendor class 2 just adds the OUI, correct?  I guess you could either 
move the SA specific header by 4-bytes, or use a 32-bit key.

It's not clear to me when to use vendor-specific versus application 
specific, but I think that we could use application specific as well. 
The mad layer just wouldn't know to enable RMPP as easily as it does 
with vendor class 2.
