Pocket Outlook APIs found

I came across a blog post by Randy Byrne, Outlook Program Manager at Microsoft, and he answered my question about where to find the Pocket Outlook APIs. It's the Pocket Outlook Object Model, described on MSDN. So now I'm curious to know what sorts of software programmers have built with these hooks into Pocket Outlook. They employ COM, which as I understand it is the kind of programming that's not for the faint of heart.
