Configure the Network from the CLI
You can configure your network interfaces from the command line using the networksetup tool. This isn't quite the Unix way to do things, but I'm hoping Apple gets there eventually.
This allows you to change all(most?) of the settings you would find in the network preference pane. To permanently change the static IP address of a given system, run the following command:
# networksetup -listallnetworkservices
This command will list all your network ports. Why you have to call them by their name escapes me, but whatver.
Next, run the following command:
# networksetup -setmanual <network_service> <new_ip> <new_mask> <default_router>
The only funk above is the network_service item. This is really just the network adapter's name. So, to set an IP of 10.0.0.2 with a subnet of 255.0.0.0 and a default route of 10.0.0.1 on my MacBook Pro's ethernet address, I'd do the following:
# networksetup -setmanual Ethernet 10.0.0.2 255.0.0.0 10.0.0.1
Note, you've gotta be root (or sudo it).
This **WILL** persist through reboots.

Leopard Tricks & Hints
So, it appears that there a lot of new looks in Leopard that people don't really like. I'm going to try and consolidate all of those here, with a fix for each. Please feel free to contribute!
Change Screen-Capture Save Location
defaults write com.apple.screencapture location /Users/YOURUSERNAME/Documents/Screenshots
Disable Transparent Menu Bar
To disable, simply type the following at a prompt in terminal:
defaults write /System/Library/LaunchDaemons/com.apple.WindowServer 'EnvironmentVariables' -dict 'CI_NO_BACKGROUND_IMAGE' 1
To use time machine over a network share, simply open up a terminal window and type the following command, exactly as shown:
defaults com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1
Now, when you have a network share mounted, you should see it as an option in the Time Machine setup options.
Time Machine Backup Interval
- sudo defaults write /System/Library/LaunchDaemons/ com.apple.backupd-auto StartInterval -int 3600
Change 3600 to the new interval, in seconds.
Dock Glass/3D Undo
If you hate the new 3D crap that Apple has bestowed upon the dock, you can disable it and get, what I would term as, a pretty darn good compromise. Simply open your terminal and type the following commands:
# defaults write com.apple.dock no-glass -boolean YES # killall Dock
Alternatively, you can put your dock on the side, and automatically get this new appearance.
