Did you know that "Windows SideShow" is trademarked by Microsoft? That means there are a lot of rules and requirements around using Windows SideShow in any text, marketing materials, logos, articles, products, etc. To help you with understanding these arcane rules, we've put together a use guidelines document which describes generally what is allowed and what is not. For example, you can't actually say "Windows SideShow device", it has to be "Windows SideShow-enabled device," "device for Windows SideShow," or some other variation on that style.
The use guideline document is posted to the Windows Vista Partner Portal, which is accessible at www.windowsvista.com/partner. Note that you do have to complete a brief registration to access this site. For those who don't wish to register, we've also got a copy available on the Microsoft Intellectual Property webpage for Usage Guidelines: http://www.microsoft.com/about/legal/intellectualproperty/trademarks/usage/default.mspx.
A direct link to the document is here: http://download.microsoft.com/download/6/8/5/6852CEA2-BC7A-4AC7-B7E9-99C13BD778C6/WindowsSideShowUseGuidelines.doc
