I would be interested in what type of information you come up with. I done a bit of Java development myself. I wonder what kind of market there is for a real time feed with a Java front end (non browser based I would think).
Up here in the Great White North we don't have the selection in firm that's available south of the border. The only two I'm aware of is SwiftTrade and TradeFreedom. Anyone have any experience with TradeFreedom?
