WOW, it would be great if you can make a webtool for it, so that it's easier to use for most people. I don't think anyone is trying to make this yet.

From the comment above, it seems that @mightypanda intends to make one if there is "enough" demand ...I dunno what it means though and how will he assess the demand for it. But a tool that can be useful and unique should get popular with time, I guess.
