It *adds* to DNS-SD, which is why this draft is so short ;)
dns-sd defines stuff like:
_http._tcp.<domainname> SRV ...... <host>
This defines:
_website._service PTR _http._tcp.<domain>
PTR _https._tcp.<domain>
Thus also allowing multiple protocols for a single service.
eg an email client could then do:
(tbird = thunderbird, user = you)
tbrd: what is your email address?
user: [EMAIL PROTECTED]
tbrd: cool, lets see what I can find out:
$ host -t ptr _email._service.unfix.org
_email._service.unfix.org domain name pointer _imap._tcp.unfix.org.
$ host -t srv _imap._tcp.unfix.org
_imap._tcp.unfix.org has SRV record 0 0 993 purgatory.unfix.org.
Protocol imap, port 993 on purgatory.unfix.org it is ;)
No more entry of manual configuration stuff. Btw, this could also work
with clusters as one can have multiple SRV records with different
weights etc.
The anycast address make it able to use the local service, then the user
only has to pass it's username, it will use _service. in this case,
though an identity based on email is likely better. DNS Search paths
allows the _service domain to come from a remote place, maybe on the
other side of the world, you still haven't configured anything most
likely.
But lets see what a lot of other folks think about this thing. Most
likely there will be quite some though comments on it.
