Since the Packaged App mechanism works on uploading full directory trees, it is easily possibly to accidentally have some w.i.p. content in the app directory that accidentally gets uploaded. For example, for a while I had made some backup copies in my app directory that I was not aware that were being uploaded to the device again and again, bloating my app size. To make the user explicitly aware of the work being done, instead of printing out 12:23:00: Installing the MyApp app... 19:34:00: Installation complete. the process should read 12:23:00: Installing the MyApp app... (69MBytes in 29 files) 19:34:00: Installation complete in 7 minutes and 11 seconds (295KB/sec).

Maybe we should add a progress bar.

Something like: > [===> 4 / 29 files (69Mb) ]

Well, no, because we only send a big zip file. So a simple progress bar with the size + number of files displayed somewhere.
