It isn't the DAO that'd be a transient - it'd be the User business object that (if ColdSpring served it up) would be a transient (singleton=false). You'd inject the singleton DAO into it.
Proviso: Some people on the lists have recommended NOT using ColdSpring for transients, but creating a custom factory instead (or I use LightWire). Others have used ColdSpring for instantiating their transients without problems.
