I beg the Org developers to please be very careful when introducing expensive display features such as overlays into Org. Org already puts the Emacs display engine to its limits in many of its popular features; adding overlays to this mess might be too much. I don't know enough about Org to understand why overlays are being considered instead of text properties, but feel free to describe the issues (preferably on emacs-devel) and start a discussion about the possible alternatives.
