You left out that SAP/SDR will not support SSM. There has been a big

IETF WG. The consensus is that source info will be communicated out of

As usual, I take the minority viewpoint. I think that SSM will NEED
something like SAP.
Just think about doing a beacon project where beacons can join at will -
how would you know in SSM ?
I think that there sorts of consideration will lead to a re-inventing of
the SAP wheel in some scalable fashion.

IPmc requires many debugging tools, builtin to the native router, to make
it all work.  Without sap/sdr capabilities, SSM will never take
off.  Having all the web pages out there are nice extras, but do not
replace the needed builtin tools.

I'm not sure I agree with this. My case for a SDP like ability is basically
a business / convenience one - i.e., it would be nice to have. I do not
see why it would be really essential. Also, if you don't believe that
ISM will
die, then neither will SAP.
