Logic Pro 9 (App Store)

I've just bought and downloaded LP9 from the App Store. When starting it for the first time I was offered to download basic contents (about 2 GB, did that) and then to download all the Jam Packs/Loops etc. etc. (7...9 GB I would estimate).

I want all these downloads, but haven't done this yet (haven't the time at the moment). I will need all these downloads on my OTHER Mac(s) too. How (wired LAN) can I copy the files there?

I hope this is possible, I wouldn't want to repeat these GIGANTIC downloads for my other Mac(s).

Many thanks for your help!
