If it's ever implemented...
It'll cost hundreds of thousands - Steve's right about the £10k to pick out the consultants.
In fact it's probably the low price tag which is putting them off - once that's been made public by some pretty professional people, the gov/civil service has got no room for the usual gold tape around everything.
Simon's point is excellent too - why not create it in XML then export it how and as needed...?
