Netflix at least could easily provide a link. When it is on a fileshare somewhere, is that something Chromecast can handle? If so it will be essentially serving the file from your device, and I see no reason you couldn't similarly ask DLNA to stream from a server you're running locally. In fact I do very much the same thing regularly (using swyh, quite a useful tool)
