We are anarchitectural firmcomposed of 25persons, and so 25 computers.
We sometimes use photoshop but it's rare.
We are looking for licence that will authorize us to install Photoshop on all computers but enable only 2 users to use Photoshop at the same time, like a network licence.
This way we'll pay only 2 licences... For example, it works like that with Google Sketchup. It's installed on all of our PC, but only 2 persons are able to open Sketchup at the same time and we pay only 2 licences.
