Hi Paul, Joe,

Thanks for the draft.  Reading through it, it seems to posit a mechanism
for providing a DNS API server that will serve the same function as a
recursive resolver would now.  Given that this is basically similar to a
recursive resolver putting up a new API, I'm not sure why the complication
of a non-standardized prefix is the right trade-off.  Why not standardize
it?  If not standardized, why not use the well known URI mechanisms?

I also note that this seems to be answering a different use case than
Patrick and Martin were talking about in regards to server push.  With
this, server push might be used for something like additional data, but you
wouldn't see this in the same context as "normal" HTTPS connections, so
server push from a content server wouldn't apply. Have I got that bit right?

regards,

Ted
