1) Do you agree with the Jamie's response to the changes I've requested
concerning the associations between policy group and SA rule? Will this

Yes, all authors agreed on your proposal (thanks for catching it)
2) There was agreement last week that the IPSec policy model does not
support address ranges in for filter entries. Will there be a fix to the
model to support this feature?
Actually, the IPHeadersFilter class is coming from PCIMe and as far as I
know PCIMe is currently extending this class.

Yes, the -05 is mostly complete (basically nothing completely new, just
minor fixed + clarifications)
