And surprisingly, it's actually very effective. I couldn't find anything out there (yet), but as it turns out, Apple has something built-in that allows you to accomplish something very close. I've been very frustrated with that, and went looking for a Mac Gem or AppleScript that would allow me to disable the trackpad with a keyboard (similar to the PC laptops that have an extra button near the trackpad).
Have you been frustrated with how the slightest touch on the trackpad causes the text cursor to jump to a different line when you're typing away, especially when you're in mid-thought and wanted to capture everything? (This only applies, of course, if you've enabled trackpad clicking.) Have you been even more frustrated when the Ignore accidental trackpad input setting within the Keyboard & Mouse preferences still doesn't work 100% of the time?
