nah, actually the way is more like dropbox work
there gonna be an update creator with login system,
the update creator will run just like dropbox, there will be a directory where all the items will be stored.
now, once new file is been puted into the folder or a file been updated, the server program will regonize it and assign it to a file structure list.
at the client side, there is nothing left to do is just to run the updater exe, there will be assigned an INFO.INI file with in it (with some encrypted data) about the server's login and IP..
basiclly thats all what it does.
