title: Technologies to implement repository similar to dropbox
body: <p>I have do investigate some ways and technologies to implement a server or client-server similar to dropbox (a simple repository)... </p>
  
  <p>Probably I'm not making the best search but I can't find the best technologies to implement or some examples or open source projects that implement the file transfer part...</p>
  
  <p>If you implement something like dropbox what technologies would you use?</p>
  
  <p>Other question is, where is the best place to store all files?</p>
  
  <p>Tks for your help and sorry for my english!</p>
