You can give public access to your wave by adding a user to your wave called email@example.com.
(How it works: easypublic is a robot that adds the firstname.lastname@example.org which is the real public user)
If you are going to create many public waves, add the email@example.com to your contacts list. You can then just drag the easypublic icon from your contacts onto your wave.
