Technology, Books and Other Neat Stuff

I'm confused. In what way is this unlike a wired protocol? You are still transferring a file directly from your home PC to your laptop. Unless FolderShare is doing some funky on-the-fly compression (and one hopes encryption too) with smart re-try on failure in some way particularly suited to mobile connections, in what way is this not like using an SFTP client? I appreciate the advantages in things like synchronisation and sharing, these can be tedious to set up with SFTP, but unless it works out your connection speed and type and alters the file transfer accordingly (packet sizes, retries, etc.) automatically, what would be the difference in transfer speed and usablility if all you are doing is copyinging a few files?
