I don't understand how to express the concurrency requirement to the prospective hosting companies. Providers define capacity in terms of MBPS. I'm sure concurrency is more complex than pipe size. I'm guessing it's a function of available bandwidth AND the size and format of the media files. Because we're talking about the Internet and not a dedicated line, I'm guessing time of day and proximity to a major hub might also be factors. Enough guessing. :crash:
