Command Line As PIM

If you have a Wiki As PIM, so you're already just looking at everything as SmartAscii, why not just use the Command Line for your PIM?

A person gets a file named as their Wiki Name. A week of calendar items get a page with its week-ending date. Instead of looking for that name, you 'cat BobJones'. Or 'vi BobJones' to edit.

I guess this is really Text File As PIM.
