title: Cocoa App: How distribute beta versions?
body: <p>Until today I've developed and tested by myself all the versions of my app!
  I would like to begin to release some versions for beta tester, to have a better product to release! But I really don't know how do that!</p>
  
  <p>I had thought to upload the beta version on my website in a password protected folder and sent to my testers a notification (by e-mail) about the availability of a new beta version.</p>
  
  <p>Or to upload the beta version on a restricted area of my website and mail to my tester a dynamic link (with an expiration time) to the new available beta.</p>
  
  <p>These are some good way or I can do that better?</p>
  
  <p>Thanks in advance for your replies!</p>

  <p><strong>EDIT</strong></p>
  
  <p>I already have some beta tester, I'm not searching for new one! I'm asking only for a suggestion on how send my beta version to my tester!</p>

  <p><strong>EDIT 2</strong></p>
  
  <p>The app I want to send to my testers is a MAC OS X application, not an iPhone OS app!
  Otherwise, I would like to distribute the app (only to my beta testers) in a secure way ... so I can't use software updates frameworks as Sparkle!</p>
