Sorry, I should have been following this thread, and weighed in
earlier.  I'll attempt to summarize my position briefly; if some
of my points are passe', forgive me.

1) Re Notify direct to the failure handling LSR (or head-end) vs.
   hop-by-hop: definitely direct.  The difference in speed between
   hardware forwarding and software looking at the packets is huge.
2) Re Notify superceding the need for PathErr: No.  Send both.
   Even if the PathErr is redundant -- what's the cost?
3) Re intermediate LSRs processing the Notify even if router alert
   is not set: allow double IP encaps, but make it a MAY (NOT a
   MUST or a SHOULD) (i.e., agree with Adrian here).
4) Re IGP for failure notification: does not compute.
5) Re Multiple LSPs in a Notify: definitely (Adrian's restrictions
   seem reasonable).

I hope the brevity makes up a bit for the tardiness.
Kireeti.
