In Maya set driven keys are the same node as normal animation keys, the animCurve node: http://download.autodesk.com/us/maya/2008help/Nodes/animCurve.html
There's a bunch of child nodes listed there with two letters after the "animCurve", which is the specific input/output that node handles. So like, animCurveTU takes input time (t) and outputs double (u). All the animator set ones are the animCurveT* ones. All the animCurveU* ones are used for set driven keys. I know this is always the maya answer but... I always did this with a script. AnimCurve nodes are almost always named after the object/attribute they are connected to. So it's pretty easy to duplicate the animCurve node, parse out the attribute from the name, find your mirrored rig bit, and connect it up. You can use listConnections to find the driver node and do something similar. Expression nodes are different. Essentially they just hold a giant string (the expression itself) and when it gets compiled Maya does some under the hood magic to make or break connections to the node. To mirror it you don't need two expression nodes (you can if you want), but you need to copy the text in the expression itself and search/replace your Lefts for your Rights. You can do this at any time and the expression will hook up to the attributes if they exist. Matt is right about using utility nodes in place of expressions if you can. Sometimes copy/pasting stuff works but it also makes a lot of garbage in the scene. Honestly with Maya the faster you can get to a scripted rigging pipeline the better.
