I'd love to hear more about this as it's directly related to the
question Hixie asked.

I take it you are sending that header from some set of URLs on your
servers, which are then loaded using XHR (XDR in IE) from other sites?

And you are wanting to (or perhaps are already) structuring that data
such that it can be used with EventSource once browsers support it,
and support using it in cross-site scenarios?

Am I correct so far?

If so, what type of data are you returning from these URLs?

Given the header you are sending, it seems like this is not
personalized data, but rather generic data which looks the same no
matter which users browser is reading it. Or more specifically, you
are not personalizing the response from these requests based on the
users cookies, is this correct?
