Hi Armin, besides off course install mapserver (and thus proj) and serve those overlay layers from there :-) you can try to learn ArcIms about this projection? I found something about defining projection info here: http://www.spatiallyadjusted.com/2006/12/10/esri-instructional-podcast-on-defining-projection-information-for-arcims-map-services/
You'll probably need information from: http://www.spatialreference.org/ref/user/google-projection/ But that's all help I can give...
