Following your comment I've read many more documentation and it seems to be BIG.
Thousand of companies are using it (Big once included).
And it seems to be a success everywhere.
Therefore I'll give it a try in our lab to see how it goes, and what we can do with it
I'll also try to find out if there are any companies in Nantes and around that already installed it and try to contact them to get more info.
Thank for you help.
