Apple had made Rendezvous available under its Apple Public Source licence, which allows users to view and modify the code. The move is expected to speed up adoption of the technology.
"With Rendezvous, our goal is to make this a technology that is applicable across the entire industry," said Chris Bourdon, product line manager for Mac OS X. "We don't want to create a proprietary networking technology here."
Some of the first companies that have pledged to support Rendezvous include Epson, Hewlett Packard and Lexmark. Each said they would release printers that could be identified over wireless networks using the networking technology.
Philips Electronics has also said that it plans to release television and stereo systems with Rendezvous support.
Rendezvous can also identify applications or services that are available on a device. For example, Apple's new instant messaging application, iChat, can create a buddy list of other iChat users in a local network automatically. If a new user appears in the network, iChat will recognise that user automatically through Rendezvous.
Apple also released the code this week for the latest version of the Darwin operating system, an open source version of Apple's commercial software Mac OS X . Darwin Version 6.0.1 brings the open source operating system up to date with Version 10.2 of Apple's Mac OS X operating system, also known as Jaguar.
Darwin 6.0.1, which was made available on Apple's Web site on Monday, can be installed on computers that run either on PowerPC processors or chips based on the x86 architecture. Darwin and Mac OS X are partly based on the Free BSD operating system, a variant of Unix.
