Rlyda,
Good questions. Would you see the scrolling as configurable meaning you could either have it scrolling horizontally or vertically depending on an optional setting? Tooltip right now just displays the company name but could be updated to display whatever other information is available via the webservice. Good idea about changing the datasource.
I must state again, however, that this was never meant as an all inclusive solution. It was more of proving to myself that it could be done. The module exactly mimics how I view my stocks in My Yahoo without some of the other bells and whistles. I'm simply offering to share it if there is merit.
