Re: Screensharing: Bootstrapping Collaboration between Capturer and Capturee

Hi Elad,

I find this API really interesting and I can understand the value for
google and other service providers. However, it is unclear what is the
benefit for the rest of the community. Let me explain my concerns.

Given that the method are opt-in, I foresee that only the web sites
interested in being captured will ever use this API, and given that the the
web sites can set the domains that will be allowed to receive that
information, it is not unreasonable to think that they will only allow for
the same company VC products.

So my worries are that we will end up having an API that will be only
enabled in google docs to be able to expose information to google meet, and
in microsoft 360 to expose information to microsoft teams, and they will be
able to provide a much better presentation experience than the rest of VC
services. I am not saying that these are Google or Microsoft intentions,
but that is a more than feasible possibility.

I understand the value of an API like that, but I think it should be a
benefit for all, not just for the ones that control both the content and
the conferencing services. I really hope that the API can be modified so
this can happen.

Best regards
