> allow them to be interoperable through clear APIs. Don't try to build a magic black box that does everything for you. One word ... licensing.

Its another thing to talk about data feeds for "open" use by anything under the sun via API. Multiply this by hundreds or thousands of data vendors worldwide who provide feeds to your Bloomberg-esque organisation and you see the problem.
