You might have to do a "get info" on that library folder and change the permissions to the new owner of that computer, then hit the "apply to enclosed items" button. Your slideshow should be there and it should play, but since I have never done it I can't tell you for sure. On the other Mac, the person has to Option launch iPhoto and choose that library to open. When done you can close iPhoto and copy this iPhoto Library folder to the other Mac. Make sure you empty iPhoto's trash often when deleting all the photos. Now you have to delete all the photos from the library that are not in that album so you are left with just the slideshow/album photos. Once the titles have changed you can go to the library and do a search for that title and select all the photos and put them in an album.

Navigate to the duplicate library and highlight it, then click open Launch iPhoto with the Option key held down until you ge the message screen is assembled when you export them to share. This is why the completed slideshow, book, etc. The separate file would have to include all the images and transitions and music. Can you imagine how the size of your library folder in the Finder would expand if you had a separate file for each slideshow, book, album, etc. You are correct that this makes it hard to transfer from one Mac to another, but this is the way that it is. All the info for books, slideshows, albums, etc is all in the data files.
