Ever wanted to quickly copy/paste your current IP address into an application? Now you can, using a relatively simple Automator Service in Snow Leopard.
Just download this file (75KB) and save as a service in Automator. This will add a new service called Get Current IP. This script gets the current default IP interface (for multi-homed systems), then pastes that result into the current app.
[robg adds: I haven't tried this one.]
