In my house, the inventory includes today:
o two printers
o TV set (via apple TV and Roku)
o HiFi equipment (my new HiFi can be controlled via phone/tablet
applications; it also does streaming audio from various services)
o I think my Blu-Ray player is also, but I've never tried.
o Home routers (a mesh)
o NAS box (clouds don't provide enough performance for most people, at
least yet).
o web server on home router gateway
o ssh services on a number of our laptops and the home server.
The following are also in the network, but are using remote web sites,
which I'm not very happy about; I'd prefer to keep these under my personal
control.
o thermostats
o scale
Most of these are Linux boxes under the covers (Linux dominates the CE
device space at this point); advertising a service is a trivial Avahi
configuration that it appears the mass market is already capable already of
usually doing the right thing to make services discoverable.
To make it concrete; some of the above devices are powered off atm, but
mdns-scan reports:
jg@jg-thinkpad:/var/log$ mdns-scan
+ jg-thinkpad [08:11:96:75:1d:94]._workstation._tcp.local
+ jg-thinkpad._udisks-ssh._tcp.local
+ andi-laptop [00:13:02:46:01:75]._workstation._tcp.local
+ Secure Shell on cerowrt._ssh._tcp.local
+ Web Server on cerowrt._http._tcp.local
+ Apple TV._airplay._tcp.local
+ 5855CA4A3092@Apple TV._raop._tcp.local

+ Officejet Pro L7590 [9D5AB9]._http._tcp.local
+ Officejet Pro L7590 [9D5AB9]._pdl-datastream._tcp.local
Browsing ... /
What is more, it's pretty easy to configure avahi to announce services for
other devices if they don't themselves, not that I'm happy to have lots of
multicast traffic going forward. *That* we need to tackle head-on, anyway.
