That's cool. I'm not sure this falls into the same scope, but it occurred to
me that it would be handy to have a DNS server that provided SRV records
based upon registrations arriving from other server programs. If the
application (say, an HTTP server) launched, started listening on an
arbitrary port, then told the DNS/SRV server its service name and port
number, the DNS server could start feeding appropriate SRV records for the

I'd have the application keep a TCP connection open to the DNS server, and
if that connection went down, the SRV record would be removed. It would work
a lot like dynamic DNS, except per-application instead of per-host.

just looking to plant some idea seeds..
