In the long run it'll be interesting to see what Red Bull does. With a product that costs $5/cs to get to the distributor's warehouse and sells for $32, that gives alot of fat to spread around and it appears that that is exactly what they do. To compete against that all you can offer is better packaging and flavor.
But even with $70K from Red Bull they could send you on your way some day. My distributor in SF makes twice that much and the only way he's going to have to give that up is if he fires himself. His eggs aren't all tied up in a Red Bull basket either so I'd say his future looks alot brighter than a Red Bull rep's future.
I can also say that Red Bull has effectively turned their product into the energy drink for the Duh crowd. Anyone I meet who boasts about the fact that they drink Red Bull can be handed a few of the bottled energy drinks I have and become an instant convert. However, that must be done person by person and this is a tedious task. Red Bull has to be commended for making themselves a staple item for those who are not aware. They will reap the financial benefit for years to come; even though I don't personally care for the product I can say that they've got themselves something which will only erode over a long time and will erode slowly due to their huge amount of expenditure in a staff that does all of the things you mentioned. These expenditures are paid for by the poor souls who pay $2 for a Red Bull; as long as they can stay above critical mass on that score, they'll control the market.
Keep in mind that the King Of Pop\'s crown is not made from a bunch of melted aluminum cans!
