Blueprint for ZeroConf

Provide automatic service discovery so that a group of Netbooks running Sahana can find each other without the need for configuration.

Overview:

• ​http://en.wikipedia.org/wiki/Zeroconf

Best toolkit to use is probably Apple's Bonjour:

• ​http://developer.apple.com/networking/bonjour
• Python interface: ​http://www-unix.mcs.anl.gov/fl/research/accessgrid/bonjour-py/bonjour-py.html
• Windows licensing agreement: ​http://developer.apple.com/softwarelicensing/agreements/bonjour.html#bonjourwin

Alternatives are:

• Microsoft's SSDP (used by ​UPnP):
  • Python implementations:

    • ​http://www.sourcesec.com/2008/11/07/miranda-upnp-administration-tool/
• Java's JINI (now Apache River):
  • ​https://jini.dev.java.net/
  • This would need us to use Java libs via Jython unless we write our own Python libs!

The Open standard, SLP, seems unmaintained:
