I would so like to see this happen (not bothered about .lit, rather go for something open like .epub). Please contact me if you could code it, I can design it and probably get it to the right people to get it on the DSiWare shop. I know this breaks the spirit of homebrew, but I really think that...
I feel like school, back when I was actually in school, was more entertaining though, because of how much I get to interact with people, hang out with friends, and other stuff like that. All I get to talk to at work is my boring coworkers lol
