Well those kind of shaders generally(But not always) require a lot of assistence from the engine/code that is using it.
Normal Mapping demos for example require you to pass mesh tangents etc. So, although it is a nice dream to be able to produce wysiwyg shaders, it's rarely as easy as that.
I prefer coding shaders myself. It's fun. :)
Jay, check out the winAPI. there's a function to check if a file has been modified.
