.mac Address Book Sharing


I am sharing my address book with another user via .mac - seems to be working well (besides being slow to update), however I noticed it does not share my SMARTGROUPS. Is there any way to share smartgroups? Or, is it possible to just create smartgroups on the other user's computer from the contacts they are subscribing to (my contacts)? I tried this and it doesn't seem to be working quite right (i.e. contacts are not going into smartgroup folder)
