Can Prism save to a web folder?

Web folders are different from network shares in that they are implemented via FTP or HTTP protocols.  Although Microsoft Office products support saving files to web folders Prism currently does not have that capability.  If you try to save to a web folder you will get an error "You cannot save in the folder you specified. Please choose another location."  The only workaround is to save the file to a local drive and copy the file outside of Prism.
