"A key benefit of Windows Home Server is the versatility and power it offers as a development platform. Even when Windows Home Server software was still in the beta stage, we published a software development kit (SDK) so that 3rd party developers could develop interesting add-ins for the product. See the original post, "Developers, Developers, Developers".

There are currently 100+ add-ins developed for Windows Home Server (up from 70+ in January of this year). We have a dedicated Windows Home Server Add-ins page on the Microsoft web site. There are also a number of other sites dedicated to this topic, such as the Forums on We Got Served and Windows Home Server Add-ins."
