I wonder if there is any consideration being given to stacking EDEN units, perhaps in environmental cabinets, in a manner that's similar to the way electronics is often stacked in environmental cabinets. The units could easily be pulled out for changing the disposable cassettes out without being disconnected in any way. Removal of the entire unit should just require a few simple connections to be released and the entire unit could be released for service and/or replacement by another unit.
