I'm fine with that interpretation of this, my concern is with the 'only
show in one group' implementation which seemed to be what was intended and
seems to be what the other people in this thread seem to want and/or
already be doing.

Yes, I'm aware of the relationship between contacts and groups. By 'buddy
list copies' I meant visual copies of the buddy, unless most clients don't
show a buddy in that has more than group in more than one group in the
buddy list window. Is that how most clients handle it? They pick one of
the groups and only show the contact in that group ignoring the others?

Or alternatively, does the metacontact apply per-group but in all groups
and thus this issue doesn't exist at all (which is a scenario I am
perfectly willing to accept).
