Corporate section

Do we want to have a corporate section?

Such a section could have any of the following features:

1- A section open only to company representatives to provide up-to-date news about their products.
2- Such representatives (or their companies) would/could/may pay for the ability to have such a membership.
3- be only about providing advertisement (products only)
4- be not only about advertisement (include discussions and personal opinions)
5- Be part of the main menu but not otherwise visible.
6- Have it's own block on the side of the main page as well as an entry in the main menu.

Any ideas?
