I finally got around to looking at trackback. Phil and Paul are right... from the perspective of the post being pinged, a trackback is simply a comment from another source (modulo naming differences, e.g., what I call "comment", tb calls "excerpt", etc.).
So by accepting either name, and adding a wodge of TrackBack mumbo-jumbo to each comment page, and it looks like I'm done! (Question: should I have added it to each entry in my index.html page? Seems like a lot of overhead to me).
Note: it looks like the norm is to ping an entry using HTTP GET. While I support this, I've also made sure that I support the more RESTful HTTP POST equivalent.
Can somebody with trackback enabled client try pinging this entry?
