simple suggestion, since you asked a complex question.
Go immediately to the South Lower Hall. This is all post production. This is where ALL the SAN
systems are. This is where all the storage arrays are. This is where all the asset managment programs are.
While there is "too much to see" at NAB, and there is a lot of stuff in the Center Hall and North Hall, it sounds like everything you want to see is in the South Lower hall. Go all the way to the back of the hall as well - don't get bored - there are a lot of amazing companies all over the place. There is a lot to see.
