mDNS/DNS-SD Service Discovery Widget

[anonhostpi]

Description

In addition to providing service discovery via docker, I think it would be worthwhile to implement service discovery over mDNS/DNS-SD.

The way I would recommend implementing this is to wrap or reproduce avahi-browse. Reason being is that not all mDNS services come with a web UI (printers, scanners, unconfigured mDNS hosts, etc). However, it may still be nice to discover what devices are on my network and what addresses they can be found at.

I would consider the following when designing an implementation:

• avahi can be a bit bugged out sometimes, and doesn't like network changes a whole lot. To get around this I would cache the service discovery results in the event that avahi acts up.
• for docker, I would implement an mDNS repeater or expose the container directly via bridged networking as mDNS/DNS-SD requires the machine to be on the same broadcast domain.

Medium (Would be very useful)
