As mentioned in the article Fuse is a good tool for building something like this but it is only supported on Unix/Linux and OSX. There is however a Windows project that does something very similar called Dokan (http://dokan-dev.net/ http://dokan-dev.net/). I recently discoverd a python libarary called pyfilesystem (https://code.google.com/p/pyfilesystem/ https://code.google.com/p/pyfilesystem/) that provides a unified API for both Fuse and Doken so that you can write the fs once and run it everywhere. What's also quite nice is that you actually create your fs as a python API first and then mount it. This results in you creating a good API that could be used inside a phone/tablet/web app, if you stick with python... The problem the OP is trying to solve is very similar to one I was experimenting with a few weeks ago but abandoned in order to concentrate on my main project that is beginning to really take off. If anyone is interested in starting a OS project around this sort of idea I would love to get involved.
