Is there a way to convert (wrap) a mutable Map to immutable in O(1) time (that is, not by copying the values, but similar to what is done in JavaConversions)

There is a read only projection for mutable maps.
As oxbow_lakes pointed out the underlying Map is still mutable and may change after the read-only projection is published to clients. The illusion of immutability has to addressed in code managing the map.
