"At this very moment, it is possible for any Joe Schmo to go over to Microsoft's server and download all of Windows Phone 7 XAP application packages without the need of a WP7 device or Zune Desktop software. This is possible because Zune software uses ATOM XML feed to grab application info, so it's just a matter of diving into the code to find the XAP package address and download it directly."
Yikes! This is probably the last thing Microsoft wants to see. The implication of this is that every app's source code is laid bare for anyone without any scruples. Developer support is one of the main foundations for WP7s success so let's hope this gets fixed soon.
