Microsoft's Windows 2000 uses SRV records extensively.  Windows 2000
servers advertise the services they offer via SRV records, and Windows
2000 clients find the servers that offer particular services by looking up
records.  So I'd have to say that Microsoft is pioneering this area.

If we could just get IE and Navigator to support SRV records, we'd take
care of a large proportion of the HTTP and FTP clients in use.  (Maybe
the version of IE shipped with Windows 2000 already supports SRV
records--I honestly don't know.)
