But SRV has been widely deployed since=85 before 2000? It=92s literally =
the backbone of Active Directory deployments. Here=92s a list of things =
that his company=92s network design probably breaks:

* Office 365 (cloud Exchange hosting by Microsoft; requires you use SRV =
records to get your company=92s clients pointed to their cloud =
infrastructure)
* LDAP
* SIP
* XMPP
* CALDAV / CARDDAV
* SMTP, IMAP, and POP clients should also obey published SRV records. =
Not sure how many clients really do, though.
* Teamspeak 3 doesn=92t force you to use SRV, but you can use only SRV =
records
* Minecraft
* Last I knew IRCv4 specs are slated to include SRV as a core feature

I can=92t speak for the caching issues, but SRV is pretty active and =
only getting more popular because things like =93round robin DNS=94 are =
a horrible, ugly, unreliable hack and things like Anycast or Geo-DNS =
isn=92t always feasible.
