As i said in my prior mail to this list (which went without any reply),
most people nowadays wouldn't even know what it means to be directly on
the internet without any firewall, and i really question whether it is
prudent to ONLY have this option and NOT document it very clearly to all
those users not working at the network level. I also think that folks
who want to test if their applications work well and invested into
ICE/STUN and other firewall traversal mechanisms (like RTCweb and other
app groups), would maybe like to have something more reflective of
relevant end-user access (with firewall).

As much as we network layer nerds may like it, we should understand and
acknowledge that it doesn't represent a reasonable end-user-device
access method to not have any firewall. And i am mostly concerned about 
all those company notebooks used in IETF which too would expect even at starbucks
to have some degree of protection against scanning attacks. At leat on
one SSID.

I am already surprised how much the IETF noc team has been able to work
with hotels existing AP and access-LAN infrastructure and make it work
as good as possible. I do not always like the results (like in
montreal), but lets not underestimate the complexity of the job of the
noc doing this.

Where would the discussion about what type of security options to offer/
document fit ?

Not sure what other think to be meetecho problems. I only thoght the
video quality from remote participants sucked but didn't get an answer
whether thats because of unavoidable remote participant upstream limits
or application level enforced uper bandwidth/quality limits.
