	The paper provides nice overview of PLA without going too
	deeply to the details. Some ideas and thoughts are listed
	below:  

	- You could discuss a bit more deeply, what makes PLA
	  IPv6-specific (as was already discussed during the lecture). 
	- In the applications, how the initial authorization of an
	  initiator is carried out. (It is mentioned, that it can be
	  achieved offline, but still, how?)
	- As PLA-provides only authentication (and integrity
	  protection), it would be nice to give some ideas on how to
	  achieve confidentiality also. Some picture of the
	  packet-structure if PLA+IPSec is used might be
	  nice. (Actually, some figure of the structure of the packet
	  with only PLA might be helpful).
	- As the paper discusses also actual applications, some
	  discussion on how to actually implement PLA might be
	  good. Such as, how to distribute the hardware accelerators,
	  how to create the trusted communication between nodes and
	  TTP and so on.
