New Mac software implements ‘discover and share’ protocol
Register report.

Jaguar, or “Jag-wire”* as Jobs pronounced it, includes new utilities and important changes under the hood. A new service called Rendezvous automatically discovers other Mac users and drops their shared playlists into iTunes’ Source panel. Jobs showed one Mac notebook streaming to another. Apple said it will contribute the discovery and federation mechanism – which offers similar functionality to the low level services of Sun’s JCP-controlled Jini, and Microsoft’s UPP – as an Internet open standard.

“You want computers to discover each other and just share stuff” said Jobs.
