I was also on vacation (four weeks :>), which delayed somewhat this mail. I
didn't want to start discussion while people were still in Finland in the
VPN workshop, and I regrettably had to leave workshop's summary session
before I could poll it locally.

I still personally feel that with the discussion about s-o-IKE, and
_especially_ the discussions regarding aggressive/main(/base) mode in IPsec
WG, it might be bad idea to select aggressive-like approach for PIC.

Why do we want to perform significant work on basis of a packet from a
source which we haven't even verified exists and really wants to talk to

This could be circumvented (at least) by changing the exchange from 3 to 4
messages and styling it after base mode instead of aggressive mode.

If someone else agrees, feel free to point it out; if it's just me, I'll
go back to my corner :>
