I was busy looking for something entirely different on SharePoint and stumbled on the following resources, which will come in handy when building proposals / response documents, architecture diagrams, etc.

http://technet.microsoft.com/en-us/library/cc263199.aspx – these are a series of models and diagrams here in PNG, JPG and Visio format that can be used as a starting point for architecture diagrams in proposals and presentations. They are based on real-world production deployments using best-practices design and architecture. They include:

• Logical Architecture Sample Design: Corporate Deployment
• Architecture Design Example: Twynham School (U.K.)
• Architecture Example: Single School, Single Server
• Extranet Topologies for SharePoint Products and Technologies
• Shared Services Providers for Office SharePoint Server 2007
• Inter-Farm Shared Services for Office SharePoint Server 2007
• Deploying Microsoft Office SharePoint Server Geographically
• Global Knowledge Management with Microsoft Office SharePoint Server
• Office SharePoint Server 2007 Data Protection and Recovery model
• Office SharePoint Server 2007 Availability model
• Upgrading Windows SharePoint Services 2.0 to Windows SharePoint Services 3.0
• Model: Upgrading Microsoft SharePoint Portal Server 2003 to Microsoft Office SharePoint Server 2007
• Model: Site Permissions for Office SharePoint Server 2007 and Windows SharePoint Services 3.0
• Model: SharePoint Products and Technologies Baseline Site Hierarchies
• Sample project plan: Microsoft Office SharePoint Server 2007 deployment
• Extranet hardening planning tool: back-to-back perimeter
• Poster: Stsadm Technical Reference (Office SharePoint Server 2007)
• Poster: Stsadm Technical Reference (Windows SharePoint Services)

There's also a MOSS and WSS 3 STSADM tech reference poster that can be downloaded from Ian Morrish's WSS Demo site (which is handy, because the redirect links on the Microsoft page above do not work).

Finally, here's a list of resources for SharePoint, grouped by resource type here - http://www.wssdemo.com/Pages/GroupBy.aspx
