I wrote my post University CV in LaTeX using TeXnicCenter/MikTeK because I have used LaTeX for my thesis and I liked the output compared to Word. Then recently I had to rewrite it completely in English and since I had no LaTeX system installed on my computer I tried to used the Europass CV http://europass.cedefop.europa.eu/it/documents/curriculum-vi...
It is a nice system because you can edit it online, it saves information in your browser so you can continue editing it and you can even reupload the PDF and repopulate the fields (it seems to have additional XML data inside).
Unfortunately I resisted just a month using it (I didn't like the spacing/format) and then decided to completely rewrite the CV (this time using Libre Office).
This is interesting, and maybe I'll give it a try, but how are you planning to monetize it?
