Golang binding for Avahi announce

[Adam Burns]

Hi Alexander,

Firstly, thank you for your work with Golang avahi bindings as well as 
contributing to the improvement and clarity of Avahi API documentation!

I have been working in the area of unicast DNS-SD and we have a 
work-in-progress prototype to allow decentralised unicast DNSSEC updates 
which includes WA DNS-SD structures.

One core extension of our work could potentially be tighter integration 
with Avahi. Avahi tools already support basic unicast browsing.

For example:

 avahi-browse -batd zembla.zenr.io
+    n/a  n/a floodgap                                      _gopher._tcp 
         zembla.zenr.io
+    n/a  n/a zembla                                        _gopher._tcp 
         zembla.zenr.io
+    n/a  n/a zembla                                        _ssh._tcp 
            zembla.zenr.io
+    n/a  n/a PTF Demo Day - DE                             _http._tcp 
           zembla.zenr.io
+    n/a  n/a Freifunk Berlin                               _http._tcp 
           zembla.zenr.io
+    n/a  n/a PTF Demo Day - EN                             _http._tcp 
           zembla.zenr.io
+    n/a  n/a Freifunk - Free Networks                      _http._tcp 
           zembla.zenr.io
+    n/a  n/a sig0namectl Homepage                          _http._tcp 
           zembla.zenr.io
+    n/a  n/a Zembla Resource Map                           _http._tcp 
           zembla.zenr.io
+    n/a  n/a Berlin - Official Website - EN                _http._tcp 
           zembla.zenr.io
+    n/a  n/a redb                                          _loc._udp 
            redb.zenr.io
+    n/a  n/a zembla                                        _loc._udp 
            zembla.zenr.io
+    n/a  n/a bluebox                                       _loc._udp 
            bluebox.zenr.io
+    n/a  n/a op6                                           _loc._udp 
            op6.zenr.io
+    n/a  n/a cephalo13                                     _loc._udp 
            cephalo13.zenr.io
+    n/a  n/a zembla                                        _telnet._tcp 
         zembla.zenr.io
+    n/a  n/a mapscii                                       _telnet._tcp 
         zembla.zenr.io


Does your work currently extend into the unicast domain (pun intended) 
as it is or would be easy to extend into?

Thanks & Regards,

Adam.
