The implementation cam= e from what is in 9front mainline and is in #G. I agree that it would be goo= d to have a manual page for it there. mDNS is running as bcast9p process and is written in Go. It's based on a Go l= ibrary and uses udp multicast support for plan 9 that is only in latest git m= aster branch, slated for Go 1.8. Go SDK in this image is 1.7.3 though. It should be reasonably stable.
