This is the sort of thing Go really shines on: network and infrastructure services that would ordinarily be provided by big ugly C programs, where the latency requirements are significant but not as bad as raw packet forwarding. If your current best alternative is a C program, I'm not sure why you wouldn't seriously consider replacing any of the following with Go (or Rust) programs:

* Authority DNS

* DNS caches

* ntp

* SMTP

* SSH

* IMAP (added later)

* SNMP

* PBX/Telephony

Fortunately, as time goes on, fewer and fewer people need to run these services at all.
