Personally, I agree with some other folks here - your market is students and people learning languages. Add really good pronunciation help - something you can hear. Make sure you integrate SRS - see Piotr Wozniak's work on the forgetting curve. (Also see Mnemosyne, Anki, etc.) Check out lingt.com - they're the leader (feature-wise) in the language learning market for Chinese... at least from what I've seen. I recommend it to friends here at college that are trying to learn Chinese. Personally, I learn English words /really fast/. I can see them once and get a definition and I'll be good for two years. This doesn't work for any other sort of information... only English words. Why? I have no clue. Anyway, my point is that no, I wouldn't see myself using it. Sorry.
