Mounting a remote folder as local folder

I have spent hours researching this and unable to come up with a solution, if anyone knows of one please let me know. I am looking for a way to mount a remote folder on a server (using either WebDAV, FTP, etc) on my Android device as a local folder so that all apps can have access to it and save and read from it as if it were just any other folder on the phone or SD card. Note that I am not looking for a way to "sync" a folder on my phone with a folder on my server, everything in this folder should be stored on the server only and read as if it were local.
