You might as well ask them to waltz around the local park naked.

Freeze requirements is never going to happen.

aztrix: Once you have the requirements, you will actually wind up with two sets of requirements and you won't even know it.

Once set will be what you think they said to you.

The other set will be what they think they said to you.

The next step is for you to put everything you have in writing, and then go back to them and hand them the document you have prepared. Tell them that this is what you understand to be their requirements.

I will be willing to bet you that they will read this and say something along the lines of, "No, no, no....that isn't what I meant. I meant [insert new stuff here]"
