I don't want to be Mr. Rain Cloud but.........
The above mentioned items are very nice to have however they require 2 other major ingredients, Money and people.
You could say that the money is the easy part, just put it in the entry fee. That works if you end up with a quality product. If not, teams will not come back.
The second is hard to find. Getting people to man those duty positions at the ball fields. You first look to the parents within your organization. Good luck there. The parents want to be able to watch their kid play ball. It is a nightmare to try to arrange a duty schedule based on when certain teams are playing and not playing. Pool play is easy but when those teams get into elimination play, it is impossible. The tournament in which I work, the main members (TD, Asst TD, Concessions) do not have any kids playing travel ball anymore. So, how do you get workers? Pay them. Now we are back to item #1, Money.
So, the main question now is "How much are teams willing to shell-out for a tournament that will provide all of those niceties?"
To get live streaming, you need to have an internet connection. If there is no available network at the fields, then you could always use an air card. Once again, money. You have to rent or buy the cameras. Once again, money. At our tournament, we use an air card for internet so we can do the live updates. When we were the first tournament in Ohio to do live updates in 2006, we ran a phone line from the concession stand to the scoring tent and had a dial-up modem. The next year we went with the air card.
Innovation is great. The above mentioned niceties are great and they can be accomplished with a "Can Do" attitude. It will take some great thinking, some elbow grease, and some understanding from the teams when the price for tournaments go up.
