That's a good question. I can see a device that pumps chilled water through tubes around serving lines, but I think someone with actual line chilling experience pipe up. These pumps aren't built to have much lift. Too much resistance and it might not function properly.
The temp control idea is simply a small cooler or container with a block of ice and some water in it. When the temp in the ferm chamber turns on the control output, it turns on the pump which pumps the ice water into the top of the ferm chamber. When the water level reaches the drain hole it flows back into the ice block to get chilled.
I have no idea how practical this is, but I can see how it might save space and maybe some money depending on the price of a CL fridge and whether or not you had suitable containers. The hardest part was coming up with a cheap pump.
