A few months ago, a friend came to me with a broken cd-rom drive and a new copy of Panther. It occured to me that I could install Panther onto his machine by running the installer on my machine and targeting his hard drive mounted over FireWire. Thankfully, Apple hasn't crippled their OS with DRM otherwise this might not be possible. The first installer disk accepted the firewire drive but the second didn't, I had to copy it's contents onto the target drive and finish the installation locally.

Thank you, Apple.

I bring this up because I've noticed that a couple of other OS X blogs have mentioned it recently and thought it'd be nice if I corroborated their stories.
