Makes sense.

Is there another mechanism that you know of to accomplish sync across devices and/or apps?

I'd tend to see that case more as a single application running across
multiple screens. Web Intents is more about passing information
between applications.

Now if the applications can use that passed data to facilitate a tight
synchronization, that's fine, but I don't think we should envision Web
Intents as fulfilling that directly. The user-in-the-loop semantics of
web intents mean they are async from the point of view of the client
and service apps, so the feature is ill suited for n-screen kinds of
time coordination.

Is there a DLNA supported mechanism for transferring cueing events to cooperating screens and/or bridging temporal reference across multiple devices?

Since this involve communication between 2 devices, I'm not sure this can be achieved only with a link (unless this is a browser feature of course, but we are arguing for a solution that can be handled by apps rather than browsers/extensions).
>> You are assuming that the content browser and the media player must be the same application. On the Windows box I am typing this message on I discover music using Windows Explorer and feed it to VLC. I might just as well have navigated to music files in a web browser. The web page would not and need not know whether I used speakers or headphones. It would not and need not know whether I played it at all. Most importantly _it would not need to consider the possibility of users wishing to do something with content_. A page using <a href type> will not be able to forget to script a button for those poor souls who want to process and/or view their content in an unusual manner. It will never find it in the situation where a common use case works, but a separate Intent button is subtly broken due to code rot. Hidden content has shown that the Web is most certainly not immune to rot.
>> When a user right-clicks or long-taps on a link, presses Shift+Enter after activating a link, or hovers over a link, the browser has an opportunity to suggest actions on the linked resource. Populating the context menu with actions a la IE accelerators would be a great thing. The Web Intents client API, on the other hand, only makes sense when a website links to content that it knows the user wants to modify externally and feed back to the linking website. All other use cases I can think of (e.g. view, phone, search, store verbatim, modify and store, modify and distribute elsewhere, and forward, share or verbatim redistribution) are or will be better served by forms, in the case of discover and pick, nothing, in the case of search for URIs with a given authority part, or hyperlinks.
