Mac OS temporary storage area for App Store installs

Mac OS uses a temporary storage area used for downloading apps before installing.  Apple made it very easy to find in Snow Leopard:

~/Library/Application Support/AppStore

Where ~ is your home directory.

However on Lion (and Mountain Lion) it decided to get creative, so trying to find the temporary files is a little trickier.  This is how I found the temporary storage for a download of iPhoto:

vger.local:~(84)+>- date ; sudo find /var/folders -name \*.pkg -mtime -1 -ls

vger.local:~(85)+>- sudo ls -l /var/folders/n8/fcgpxxl55dgdwz6fphbd5f_40000gn/C/

It will be there only during the download.
