Not possible on a basic LFS system, but as Jeremy suggested, take a look at Screen. It doesn't allow you to migrate programs using an existing tty, but if you expect to need the feature, you can start a screen session to run your commands, then detach the screen session and re-attach in a different window. My usual use for it is to ssh to a computer at work from home, kick off some long-running command, and detach - then re-attach it on a local xterm once I get in to work the next day. It's also good for when you don't need to move between computers, but have to deal with an intermittent network connection. Simon.
