Remote participant registration was briefly — and accidentally — closed but it
has now reopened. If you plan to participate remotely at IETF 99 you can
register here: https://ietf.org/meeting/remote-registration.html.
Please note that registration is now required for all remote participants.
There is no fee to participate remotely but you will need to enter your
registration ID before you will be permitted to join the Meetecho session.
If you do not want to register as a remote participant you can still audit the
sessions via the audio streams, which you can access from with the meeting
