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.)
By the way, with mosh we can have persistent shell over changing IP address, is there a text editor that would work with SFTP in a similar persistent way?
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?
