Bonjour
From WPKG | Open Source Software Deployment and Distribution
Silent install for Apple Bonjour 1.0.5, a library for finding resources on the local area network.
The GUID below will need to be updated for different versions of Bonjour; luckily, the library appears to be quite stable at the moment (only one release in the last 12 months or so).
