	I would use two tools to accomplish this, screen and the -f option for
emerge. The -f option (ie- "emerge -f world") fetches all the files
needed for that particular emerge process, but does not go on to compile
them. This is handy for use on dial-up systems where big idle times can
cause problems. Whenever I am running on a flaky link, I do "emerge -f
blah && emerge blah", this runs the fetch and install one right after
the other. The install will only get run if the fetch succeeds.
	Screen is a real gem for remote administration. Basically, it allows
the same functionality of virtual terminals over a single ssh
connection, and (the real nice part) anything running inside a screen
process does not die if you disconnect. First install it "emerge
screen", it's small so it won't take long. then just type "screen". It
will look like it just cleared the screen, but now you are running a
shell inside a new screen session. To create a new "vt" hit "ctrl-a"
then "c" (for Create). To switch from session to session hit "ctrl-a"
then "n" for the next one, or "ctrl-a" then "p" for the previous. To
attach to a running screen process that is detached, type "screen -r" at
a command prompt. These basic commands will get you going, but there is
a lot more.
	Nice to see another Gentoo user on the list :).
