Project Geocode Results

When using the "Geocode an Address" sample from the 1.6 version of the JavaScript API, I would like to use the ESRI_Geocode_USA locator as listed but show results on a local map service that has a different spatial reference. Can anyone assist with the best approach?
Thanks in advance.

Thanks Alex, I appreciate the quick reply. I was pretty sure that the geometry service was the way to go, I just couldn't find an example that was enough like mine to borrow from. I used the links you provided and attempted to figure it out my own but was unable. Would you happen to have the time to drop a few lines of code here to help me out? Usually I would try and try until I had it working but I'm on a huge time crunch for this.

Thanks again,
Richard
