I like the idea of having remote portage in a company. Servers environment and internal strategy can grow so much that you need speed up syncing and downloading the packages. Also to have owe portage category with internal utils apps, this give yoyu ability to emerge or upgrade your app on individual servers much faster.
So go ahead and make your gentoo portage.!
Setting Portage Server
vi /etc/rsync/rsyncd.conf or /etc/rsyncd.conf
pid file = /var/run/rsyncd.pid
use chroot = yes
read only = yes
#motd file = /etc/rsyncd.motd
[gentoo-portage]
#modern versions of portage use this entry
path = /usr/portage
comment = Gentoo Linux Portage tree mirror
exclude = distfiles/ packages
option: vi /etc/rsyncd.motd
Hello Message
vi /etc/conf.d/rsyncd
RSYNC_OPTS="--config /etc/rsyncd.conf --address YOUR_IP_MACHINE"

/etc/init.d/rsyncd start rc-update add rsyncd default
setting clients servers to point to new new portage server [vi /etc/make.conf]
