golfho, I will not claim that I know the cost of the webcasting, but it will very probably be more then the bandwidth, server and hand & eyes.
Since in a way it is kind of advertising to investors that the organizing party has in their client portfolio, they will probably reason that broadcast is not aimed perse to retailers but to non attending investors.
I would not be surprised that they have some pricing behind this based on how many of those you can reach.
And in that case, we may be taking 25/50K, IMO (again, I have NOTHING to support this price wise).
