I did in another post, probably the "mentioned yesterday" one. I'm not
talking about distcc, although it does use that also. I have a copy of my
Eee in a directory on my desktop that I chroot into in the same way that
you do for installation. FEATURES includes buildpkg and $PKGDIR is an
NFS share accessed by bother. Then I just do emerge -u @world in the
chroot followed by emerge -uK @world on the Eee.

There's a little more to it than that, I also sync /etc/portage
and /var/lib/world* from the Eee to the chroot in the script that starts
up the chroot.

----------
#!/bin/sh

rsync -a --delete krikkit:/etc/portage/ /mnt/eee/etc/portage/
rsync -a --delete krikkit:/var/lib/portage/world\* /mnt/eee/var/lib/portage/

mount -t proc none /mnt/eee/proc
mount --bind /dev/ /mnt/eee/dev
mount --bind /usr/portage /mnt/eee/usr/portage
mount --bind /mnt/portage /mnt/eee/mnt/portage
mount --bind /var/tmp/eee /mnt/eee/var/tmp

sudo su - -c "chroot /mnt/eee /bin/zsh"

sudo umount /mnt/eee/dev
sudo umount /mnt/eee/proc
sudo umount /mnt/eee/usr/portage
sudo umount /mnt/eee/mnt/portage
sudo umount /mnt/eee/var/tmp
----------

/mnt/portage is the NFS share containing $DISTDIR and $PKGDIR.
