I am working on integrating http://smietnik.xon.pl/txtgtd/ into ikiwiki.

I made some progress, but I am not really sure how it should work. Basic functionality like generating a next actions list is already available.

Look:

[[!gtd  data="""
Some test project
 o clean garage @ home
 o buy nails @ errands
 o nail new frame @ home
"""]]

Produces:

[[!gtd data=""" Some test project o clean garage @ home o buy nails @ errands o nail new frame @ home """]]

What do you think?
