Is it really a good idea to tag the speed limit with a value? Say the government decides to decrease the speed limits of all rural roads with 5mph (e.g. to reduce CO2 emission), then you have to correct the tagging on all roads. And it can't be done using a script, since some roads with the same speed limit value maybe shouldn't be changed. I think it would be better to use a road classification scheme for speed limits; then the mph value only needs to be changed one place, namely the database entry that ties a certain classification to a speed limit.
