It would be great if you could share smart albums the same way you share normal albums.  
 
I shoot sports events and when go through the shots I tag them with the club of the athletes and then set up smart albums to populate photos based on keywords.  The problem is I can't then share these albums and have to take a static copy of the photos and add them to normal album which I then share.  This is not ideal as the normal album  is a static snapshot in time where these events go over 3 days so as I tag more shots I need to repopulate the static album from the smart album. 
 
It would make much more sense if smart albums could just be shared (please please please)
