Bill Seitz : If you have a Wiki As Pim, so you're already just looking at everything as Smart Ascii, 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.
