[Elecraft] K4 remote; how easy to set up?

[Macy monkeys]

I understand the K4 can be remotely controlled by another K4 via a direct ethernet connection. How easy is this accomplished with the K4? Is the operation on CW and SSB seamless provided a decent connection is available? 

I may wish to remote between two homes at some point and having the remote K4 operate exactly like I was sitting in front of one at home is what I want. I accomplished this with the Remote Rig boxes and my TS-480SAT but that was long ago. 

I only need the K4 for operating CW and SSB ragchews. I need to be able to plug a mic, key, or bug into the remote K4. I need to spin the VFO and tune around. Just like I was sitting in front of the one at home connected to the antenna. I ragchew a bit, listen a lot, and that's it. 

I'm looking for SIMPLE. I needs it to be EASY to set up. I'm not into in-depth techno geek BS. I can configure the router if given exact instructions. My brain and vision are not what they used to be :)
