Is Bonjour supposed to make your home networking a lot easier? If Bonjour is installed on all PCs, Macs, is it supposed to make home networking a lot easier?  (the heaven of seeing all shared folders any where at home?)

(even the VLC Streamer on iPad claims to use Bonjour)

But now I go look for Bonjour, and Apple is saying it is a printer service:

Bonjour Print Services for Windows
In a word, yes. Printing is only part of it. http://www.apple.com/macosx/what-is-macosx/core-foundation.html gives a short description, and http://en.wikipedia.org/wiki/Bonjour_(software) is a much more detailed one.
