@streakmachine Yup: https://mosh.org/ (used to be mosh.mit.edu)
I've had a connection with it, closed up my laptop, gone from work to home, opened it back up, and been still connected. It's pretty nifty. It also feels more responsive due to the local echo, especially over a slow connection.
It does require you run a mosh server on the host, though, so it's no help on machines where you can't do that.
