This is another step in the right direction. However, it still sounds like you need to have the actual UMD in the drive. That makes sense on one hand. But I think there should be an option to completely dump the game. Sure, some will argue that you can then just sell or return the game once its installed. But not many people have 16GB memory sticks for their PSP to store a dozen or so games. People will need to hold onto the UMD copy so they can free up space on their memory stick eventually and not lose the game forever.
