We run fully a referenced animation pipeline and all connections / animations go via the characterSet.... it does need a little babysitting though.
It also depends what version of Maya you tried with chSets. With each release more of the killer bugs get squashed, 2011 has a few specifics in the way the sets are handled and reconnected with referencing. In theory the sets actually make it easier and more flexible for rigging as nothing is name based, unlike normal referencing. All the connections and refEdits go via a placeholder list which is generated from the initial order of the characterSet, broken down into linearValues, angularValuese and unitlessValue lists. The key to it all is maintaining these list orders, referencing just connects animcurveTL to linearValues[122] etc. Right at the start of our pipeline we wrote a characterSet saver, which enables the riggers to always force the orders of the set to be consistent, after that everything is relatively safe. We get a few failed files from time to time, but most of them we can recover, and it's normally as a result of an updated source rig with a duff chSet order in the first place. Some of the GoldenEye cutscenes are huge, 5000frms, all dense MoCap data, 10-15 full rigs + props and all referenced. If you can tame it, it's a great production time saver. I do have to say that the initial love that the guys had for AnimLayers has disappeared, and all of a sudden they're running back to Trax due to bugs in the way the layers are handled.... and the lack of decent methods to remove the damn things once made!
