Well, as James knows the whole nickel and dime routine of having to get ZLC(s) to begin with chaps my a__ to no end. BUT, with that said; if one were satisfied with having the Live data on only one unit while it was being mapped using AC Live, can you simply copy the data to another ZLC after the fact; even offline using PC or perhaps an offline copy from slot 1 to slot 2 on the unit?? And then have it on two separate ZLCs, one in each unit?
