TiVo has something similar to the WMC extender called the TiVo Mini. It allows you to watch all content, even protected content, in another location in the house.
The download function of the Stream has the same limitation as TiVoToGo with DRM, as does the out of home streaming. Content marked as protected can only be streamed inside the home either to a iOS/Android device or a Mini.
