Use the "screen" command. In essence you would ssh to your target machine, issue the screen command, run your command, detach from the command by using the "<CTRL-a>,d" sequence, then exit from the target machine. Later you could ssh to your target machine, issue the "screen -list" to see your detached session(s) and issue the "screen -r <desired-session>" to reattach to the previously running session. See "man screen" for more details.

Or, if you'd rather do this in a GUI where you can see more than one open window at a time and the only reason you don't is that ssh works better over slow connections, try freenx and the NX client that you can download from http://www.nomachine.com. This lets you start a whole desktop that you can suspend and reconnect and it works very well over remote connections. You can, for example, start a bunch of things in different windows (perhaps even xterms ssh'd to a bunch of other computers), suspend the session, then reconnect from a different place (and perhaps a different client platform) and pick up with everything still running. And it can work where only ssh is allowed in. The initial start-up on a new connection is slower than screen of course since it has to draw the GUI screen, but it is very snappy after that and you can see all of the desktop windows at once if you were doing more than one thing, where with screen you would have to switch among them.
