Margaret,

implement PCP?

Yes.  A home EMS that is part of SEP2.0 may implement PCP client for
its external broadband connections.  Since a home EMS is a typically a
constrained device, it would be a burden to implement two different
protocols both carrying EAP over UDP.  By using PANA over PCP, such a
device can significantly benefit from code-sharing to carry EAP over
UDP for network access authentication inside 802.15.4 HAN and for
doing PCP for broadband connections.  This also shows why re-inventing
the wheel is a bad idea.
