Re: [Driu] [DNSOP] [Doh] Resolverless DNS Side Meeting in Montreal

[Patrick McManus <[e-mail]>]

yes; and.. dns has always provided a point of indirection that is useful.
dynamically rewriting markup might be infeasible.. and many fetch() like
things are driven from script where the markup changes are not obvious or
perhaps ill fitting.. and of course there are questions of cached content
that might like to late bind. so lots to think about; but the markup
example is very illustrative of a very conservative way of scoping things.
perhaps too conservative. worth exploring.
