You can find links for Access Manager Policy Agent 2.2 for Microsoft Internet Information Services 6.0 With Outlook Web Access 2007/SharePoint 2007, both the download and the document, on my Policy Agent 2.2 Documentation and Downloads page. This agent is a 2.2-01 agent.

For a while now, the IIS 6.0 agent could be used to protect Microsoft Office SharePoint & Outlook Web Access, but previously that only applied to Outlook Web Access 2003/SharePoint 2003.

So we've all got this going for us anyway!
