The biggest problem with purchasing RTEncoded content is that it only works on a specific version of the figure. I don't know if RTE is less sensitive to figure versions than Objaction Mover (which won't work if just the date is changed in the file), but I've run into some content that requires finding an older version of a figure to correclty work, requiring some trial and error to find which one works. That then sticks the purchaser to figure out how to transfer that content to the most recent version of the figure.
