Hi, I assume there is no interest in making DNS SRV mechanism exposed
in http://tools.ietf.org/html/draft-ibc-websocket-dns-srv-02 part of
the WebSocket core specification, neither referencing it (in the same
way RFC 3261 "SIP protocol" mandates the usage of RFC 3263 "Locating
SIP servers").

As said before, making such DNS SRV specification an extension (so
present in other document) will mean no success at all, as WebSocket
client implementors (i.e. webbrowser vendors) will not be mandated to
implement it and service providers could not rely on the support of
DNS SRV in web browsers. So nobody will use them (because IE10 decided
not to implement it, for example). IMHO this is sad due the real
advantages DNS SRV provides for a protocol like WebSocket.

Yes, in HTTP there is no special DNS stuff, all the load-balancing and
failover mechanism are done at server side with very complex and
expensive solutions (www.facebook.com resolves to a single IPv4 !!!!).
The question is: should we also inherit every HTTP limitation in
WebSocket?

Thanks.
