Request for joint meeting at TPAC

Dear W3C Colleagues:

This is a request for a joint meeting from the Accessible Platform
Architectures (APA) Working Group. We note that both our WGs are meeting
Thursday and Friday at TPAC, and we would appreciate an hour of your
time on several accessibility topics of joint interest.

Most critically we in APA are concerned that implementations of WebRTC
support cann support the Real Time Text (RTT) protocol being required of
telecommunications providers in the U.S. by the Federal Communications
Commission (FCC). There are several wrinkles to this requirement,
several of which are addressed in the forwarded message below. We want
you to be fully aware of the requirements as they currently exist, and
their impact on persons who are deaf or hearing impaired (primarily).

Beyond this most immediate concern we have been developing several
accessibility related use cases we would hope you can address in future
revisions of WebRTC, if not already supported. An early draft of our
document is available here:

https://www.w3.org/WAI/APA/wiki/Accessible_RTC_Use_Cases

Please advise if and when we might meet during Thursday or Friday of
TPAC.

Thanking you in advance for your consideration,

Janina Sajka, Chair
Accessible Platform Architectures (APA) WG
