bonjour

Wide-area Bonjour and Bonjour forwarding are things.

The same is true of bonjour probes; they'll request, then again 1s later, then 3s, then 9s, and so on.

A small program that half a dozen people can install, that spots each other by Bonjour and...

These devices don't have DNS They should, via mDNS AKA Zeroconf AKA Bonjour AKA Avahi.

Have a WiFi enabled device that uses Bonjour to auto-upload when you are at home, and iPhoto can go and index the visual record based on who.

But I think Bonjour may be the biggest winner if WiFi Direct wins since, unlike Bluetooth profiles, WiFi Direct doesn't include any application layer.

My startup's a Wide-Area Bonjour service (DNS with client updates, long lived queries and a convention for service discovery) which squares it in the client/server camp although it does have a web interface.

That is true, but I also believe there are some lower level "nice to haves" they enable on their routers to make sure Bonjour/mDNS works properly for airplay.

All the while they are meeting and sometimes surpassing old functionality with software that makes networking a lot easier (bonjour, time-capsule etc.) While slashdot is lamenting the lack of "options" apple is striving toward a machine with no ports and no keyboard.

When they plug it in, the RPi gets an IP and announces its availability via DNS-SD (Bonjour/Avahi/etc.).

Bonjour frequently stops working for a wide variety of reasons related to the switch to discoveryd.

Bonjour on the mac was really cool when everyone was implementing it.
