Well, the problem with this is shared libaries etc that might differ on
the two systems.

Well, I believe that the right way to do this is to have a chroot on your
faster computer where that chroot is insync with your laptop-system. That
way you will not get this problem nor a few other that is easily achived
when one tries to optimize for different architechtures/models in the same
build-tree.

How to make a chroot is quite well described in the
Gentoo-install-documentation. Replace the download and extraction of
tar-archive with copy system from laptop to chroot-dir on your faster
computer. ("rsync -e ssh" with some more parameters, might work well.)

Then if you compile all your packages on your faster computer, cp the
package to your laptop and install them, it'll all work fine, I hope ;)

Good luck!

Christian
