I also know that there's this (http://www.tomorrow.do/ ), which I'm assuming is based on Do it Tomorrow, but there's no credit to Mark on that site that I could find, and I don't know how Do it Tomorrow works, so I can't tell if it's similar.

As far as I can make out from the app description it just consists of a to-do list for today and a to-do list for tomorrow. You can add tasks directly to both, but it's very easy to move a task from the today-list to the tomorrow-list. That seems to be about it. There's a superficial resemblance, but I wouldn't go so far as to say that it is based on Do It Tomorrow. Not unless there's a lot more to it than appears at first sight.
The ones I know of are Andreas' 5T web app (http://www.andreasmaurer.net/public/apps/5t/v1/ ), the variant (http://www.andreasmaurer.net/public/apps/5t/variant/v1/ ), and of course his FVP web app (http://www.andreasmaurer.net/public/apps/fvp/ ).

Are there any others?
