Something I couldn't find a clear answer on...

Is WinRT going to be the go-to means for all application needs ? from interactive apps to system maintenance and "server" applications ?

Is the intent that you should be planning to change over to WinRT even for services (webservers, ftp server, database server, etc) and typical maintenence apps (anti virus, disk defragmenting, backup/restore, ...) somewhere in the forseeable future, or will those continue to be built around the Win32/Win64 api's with WinRT for interactive apps only ?
