I dont agree that wikipedia should have frozen pages. My thought is that all of the 'approved' articles be copied to Nupedia, where you can have a fixed reference.
At Nupedia, they can then undergo peer review, and then published as 'qualified' articles. I know that the current review cycle would have some problems with the amount of change that wikipedia generates, but Nupedia is the place where stable, if not the greatest in the world articles should be referenced.
A suggestion: Perhaps it means that nupedia will have to change a bit and show 'non-reviewed' articles, but it would let the wiki process at wikipedia continue.
