Re: [atoca] The future of atoca

There is significant regulatory interest in exploring IP-based options, so I would encourage taking stock and looking at a variety of options. Even a summary of the options and why they do NOT work is useful. Some initial questions that push beyond the SIP message space:

One of the bigger problems with CMAS (cellular alerts) is the short message size, which provides only very limited actionable information.

Can we leverage IP-TV style multicast for scalable distribution? How would the equivalent of EAS work in an IP video environment?

Can we separate the common problem of in-area alerting (subscribers in a particular area) from the less-common problem of out-of-area alerting ("elderly relative")?

Do we have any real experience with the realistic limits of web-based flash crowds? If every household is watching entertainment (or Olympic) video at night, the additional load of adding reasonably-detailed information may not be all that large and CDNs are used to large crowds.
