The way I'm doing this now is with a Markdown (and FoldingText .todo mode) export which I've added to what was originally an OPML exporter.

The Applescript is a wrapper for a standalone Python script with options for filtering which data you export, so you can either select something in the GUI and export it with the Applescript, or use the Python script with something like Hazel to run a regular batch job (or two).

Let me know if there are any adjustments to the Markdown output which seem desirable.
