iSSH has an independent proprietary implementation of the mosh protocol as an in-app purchase. (mosh itself has license terms explicitly permitting redistribution on the App Store, but nobody has done the port yet.)
I mean, suppose I work on a project, close the laptop lid and some time later, open it. I might have a new IP, or in general the SSH connection might have been terminated.
In that case I would have to reload all the files in the project. Would it be possible to do IP hopping and maintain the SFTP connection unterminated?
I use Mac OS.
