Parent/Sibling caches

Hi,
        i was wondering if there was any info anywhere on how to configure
parent/sibling caches. We have a guy whos on a perm connection with us and
is running his own local cache. We want our cache to be a parent of his and
his to be a sibling of ours, what other options do i need to enable in my
cache for this to work?
