That's what I do.

ZeroTier can take care of that, or a VPN if you feel like doing the work
yourself.

How tight is space? eclean-dist only removes distfiles for packages that
are no longer in the tree. So you can run it on one system and keep
$DISTDIR reasonably trimmed. If you use the --package-names option, it
will do as you suggest and only keep files needed by the machine running
the command.

If you run this on each computer

emerge -epf --usepkg=n world | awk '/^[fh]t?tps?\:\/\// {print $1}' | sort -u | while read f; do
        touch --no-create ${DISTDIR}/$(basename ${f})
        done

It will touch each file needed by an installed package. Then you can
simply delete all files more than a day old (or longer if you want to keep
some fallback)

find $DISTDIR -type f -mtime +3- -exec rm "{}" +
