Finally got a chance to play this afternoon/evening. Have installed/enabled the OpenID Provider module, which allows you to use your user account at iww.org.au as your identity on other web services. On your user page, you'll find your OpenID URL which you can use in place of a username and password on other sites which support OpenID.
One such site is the new IWW Australia microblog. Don't know if this will prove popular, but it's worth a try, if only to find out if it's possible for revolutionaries to express any idea at less than manifesto length. It runs on free software called Laconica, which is similar to but better than Twitter.
