I was thinking about a pull-modal where the data is dynamic (probably endless) so a file would not be the best solution. Just as an example, I would like Notepad to be able to read from the pipe. So I would click File -> Open then type in \\.\pipe\mynamedpipe and click Open. Notepad then would show me some data that would be produce by a Windows Service or a application that is running in the background.
