Beyond the convenience for rig management, it also could save few $ in lan ralated stuff (still have to check feasibility)
I would recommend you look at the Simple Rig resetter made and sold by Tytanick in the threads here, especially if you plan to scale your farm up, as his device can manage 8 systems for an asking price of $95 or $12 per system, and if you scale up from there, the cost per system can go down to under $8 per system.
