I already added memberlist/instant messenger to 0.9c so that was not new to me. It looks pretty good also.
Here is another suggestion, you could have an icon where the profile / email / www , etc is and have a 'Add Buddy' type icon and it would link to $CGIURL/buddyadd.cgi?sendto=$name so you can quickly add buddys to your list and will help show users to use the list more.
Thats all my suggestions and comments as of now. So far i have not seen any bugs or whatnot but will look more into it. I think the code could be cleaned up a bit more to make it run more effiently thou.
