The CS3 Installer does not let you run Photoshop on any other system but 10.4.8. If you have two machines, and one has 10.4.8, just simply copy over the /Application/Adobe Photoshop CS3/ folder and /Library/Application Support/Adobe folders… and magically, it will work.
If it says something about Invalid Product key or Invalid Install - see this link, how to manage this problem

Remote download with Bittorrent on the Mac
Friday, January 5th, 2007I usually hang around somewhere, and someone shows a cool app or movie I want to get, as soon as I arrive home So for remotely downloading via bittorrent, i use these steps:
1) ssh to my mac box with any console application
2) type “cd /Downloads”
3) type “wget http://the.torrent.file.i.want.to.download/file.torrent”
4) type “open /Applications/Bittorrent.App &”
if Bittorrent.App is running, it just simply adds the file to it, and starts the download.
