Sleep-deprived, insomniac thought for the (wee hours of the) day:

Since Dave Winer's OPML editor makes constructing and manipulating outlines quite simple -- simpler and more elegant than accomplishing the same task in PowerPoint -- I wonder how hard it would be to create a tool to automatically convert an OPML file to a PowerPoint presentation.... I wonder if PowerPoint in Office 12 will be able to import OPML files.... Perhaps not what Dave had in mind, but it would sure be cool.

Back to bed now.
