Michel,

>Yes, and I have seen at several occasions that they want to be on the Web without any specific justification given at that time. <s> Yes, I understand that being on the Web is to be ready for such a need in the future but what if they don't ever need to be on the Web, this would mean they would have invested for nothing.

With a well-designed framework that is flexible, there doesn't necessarily need to be a significantly greater investment.
