WG/Authors Opinions please :draft-cruickshank-ipdvb-sec-req-03.txt

The authors have posted a new revision of their requirements I-D with 
arequest to make this a WG I-D, as discussed at the IETF meeting in 
Montreal.

I have a few questions that I would like to see clarified by the WG via 
this list and/or the authors before this can proceed. These are:

1) Could the people on the mailing list clarify which SPD selectors we 
think should be used (NPA/MAC address, SID, etc), detailing the various 
options and needs, including what happens when we use the bridging 
header, and whether policy also can be determined based on the Type 
field in combination with a NPA/MAC address.

2) Can  we determine precisely what we man by a "Stream". Does a Stream 
always only have ONE originating source? That is, does the PID imply a 
specific intended source?

I'd really like to see a section on what constitutes a stream - for this 
the  list needs to agree if a stream has only one source (or may have 
multiple sources), etc. This section should also elaborate how data can 
be inserted in a stream during an attack and say (if you can) how 
significant this threat is.

3) Is there anything else that may be missing from this document?
