If you dont have any comment anchors in the text, how would you know which noweb block you are in? If your org file and raw files are synched, then you could, but if they become unsynched, which is the way it should be (change raw code until done, then detangle to org), i dont exactly see how you can do it. The only option which allows someone to change the raw text file is to use comment anchors - or you could save marks in a separate file, but this wouldn't allow for offline editing unless you open it with a program that understands this format. With the comment method, you get the raw file advantage, plus emacs can hide these comments if one makes a minor mode to do so - a win win situation, i think, except for the aforementioned shortcomings.
