One thing you might try is using screen.  The screen program lets you
multiplex terminals in a single window, but the feature you want here
is that it allows you to detach and reattach to a session.  So you
could start a screen session at work or home, start something running,
detach, and then come back later and attach to see how things are going.

However, screen may further complicate your desire to use X11(), but
perhaps with Xvfb run from the screen session things will work.  Do
all of the graphics devices require access to X11()?  I thought you
could use pdf() for example, without X11() but I'm not certain.
