How do I enable a user to share my URL to their stream in Google+ (Plus)?

Does anyone know if there is anything available to enable the sharing of a URL to my stream in Google+ much like the options in Facebo开发者_开发知识库ok or Twitter?

I have found documentation on how to +1, but nothing on how to share to a stream. Is there anything available yet that anyone has come across?

The +1 button now allows users to share URLs to their stream: http://googleblog.blogspot.com/2011/08/doing-more-with-1-button-more-than-4.html

Google+ now has a range of Share buttons, a Share bookmarklet and a custom URL Share Link which are documented here: https://developers.google.com/+/plugins/share/

These all allow users to manually share your content to their stream.
