IPhoto/Aperture 1.5 Integration questions

Question

Aperture 1.5 allows you to keep iPhoto pictures where they are with a "reference" from Aperture.
But since I upgraded to Aperture 1.5, I have the opposite problem -- how do I keep my pictures in Aperture but have iPhoto reference them? With previous versions of Aperture I already copied in all my iPhoto pictures and subsequently got rid of my iPhoto library (to save space).
However, I would like to use iPhoto for its better Slideshow capabilities and FrontRow integration.
So here are some questions:
[1] Should I just set preference in iPhoto to not "Copy files to iPhoto Library Folder" and import the entire Aperture library?
[2] Will it copy the albums from Aperture intact?
[3] How much additional disk space (if any) will this use up?
[4] What is the signifcance of setting up previews in Aperture (which I have done)?
[5] In iPhoto I see that there is File>Show Aperture Library... where I can see thumbnails of my Aperture pictures. What else is this used for? (i.e. can I import pictures using this feature?)
[6] If, subsequent to import, I add to the Aperture libary, will that automatically synchronize with the iPhoto library, or do I have to iPhoto-import the entire Aperture library every time new photos are added to the Aperture library?

Answer 1

[1] Should I just set preference in iPhoto to
not "Copy files to iPhoto Library Folder" and
import the entire Aperture library?
[2] Will it copy the albums from Aperture intact?
This will work if your Aperture library's masters are stored by reference. However, it will only copy the masters, not an album structure. It won't copy your adjustments either. Just the masters.
[3] How much additional disk space (if any) will this
use up?
iPhoto will build JPEGs for each master image, so you will use some disk space.
[4] What is the signifcance of setting up previews in
Aperture (which I have done)?
Previews will allow you to browse your Aperture library in iPhoto. You can decide what images are made available to iPhoto. These are the versions, not the masters, so adjustments made in Aperture will be seen by iPhoto (as opposed to importing the masters).
[5] In iPhoto I see that there is File>Show Aperture
Library... where I can see thumbnails of my Aperture
pictures. What else is this used for? (i.e. can I
import pictures using this feature?)
You can drag images from that window into iPhoto, which will import the JPEG previews so you can use them in slideshows, etc.
[6] If, subsequent to import, I add to the Aperture
libary, will that automatically synchronize with the
iPhoto library, or do I have to iPhoto-import the
entire Aperture library every time new photos are
added to the Aperture library?
There isn't any automatic synchronization, but I think the following is a good approach:
1) When importing your masters into Aperture, don't have Aperture copy them from the CF card into the library. Instead give it a folder to copy them to. In addition, specify a sub folder that is "Project Name". By doing that, your import will be separate from other imports.
2) Make sure iPhoto is set to reference images not copy them into the library.
3) Then, when you want to synchronize with iPhoto, just drag the directories containing the projects that you want synchronized directly to iPhoto.
