And you propose they run around logging into the App Store and download lion ? You're suggesting they break the terms of the license by installing 1 copy on multiple computers when that is not allowed for commercial use ? You're suggesting they forgo their NetInstall infrastructure in favor of the MAS, completely outside the corporate LAN ?
I think you shouldn't tell people that they have no place in IT if you don't even understand the problems faced with the current, only, installation method officially announced.
These companies will license their upgrade with Apple however they have done it in the past and distribute the upgrade through whatever mechanism they currently use. The licensing mechanisms used by these organizations were never publicly announced in the past. Do you think they went to Apple.com and ordered 250 copies of snow leopard?

They have not updated the pages yet but they will. Perhaps they are planning an enterprise Mac app store to go along with the enterprise iOS app store. Apples public announcements cover the consumer market because it is massive and harder to reach. In business and education one person can represent hundreds or thousands of users.
People really need to stop basing complaints on use cases that they obviously do not understand and obviously do not affect them.
The install file is an "App bundle" that resides in /Applications. That is the self-contained application bundle.
The app you're sold is not Lion the OS, it's Lion the installer. You simply run it as you would any other app.
There is a complete bootable dmg image in the location another poster just mentioned.
