I would love to see JunOS style status for each BGP session. That way I would be able to immedeatly see how many prefixes I am getting from a peer (received), how many come through my filters (accepted) and how many prefixes are really activated (active). Also I could see how many prefixes I am announcing.
Yeah and if I also could get these statistics via SNMP that would be really great! So I could graph those data 
Here is an example from a Juniper device:
Active prefixes: 366644
Received prefixes: 801938
Accepted prefixes: 801938
Suppressed due to damping: 0
Advertised prefixes: 8
