Now that we have your code, is there any chance we can get some sample data? :) I'd really like to play around with this, just for fun more than anything. Not trying to be pushy, just curious.

PS: just a few lines of example data will suffice. I'd just like to see what form the data is in, then I can synthesize some on my own. It wouldn't exactly be representational of your data, but it'd be something to play with.
