You can use the new NBAR Qos tools to identify kazaa and then police it.
NBAR is in 12.2,  and is used to classify/identify dynamic protocols.   Once
in a class, you can create a policy map .
Something like this
class-map match-any mykazza
!  fastrack = kazza, morpheus etc.
    match protocol fasttrack file-transfer "*"
! police to 8kbs
policy-map squash-kazza
    class my-kazza
          police 8000
int e0/0
   service-policy input squash-kazza


(if that link doesn't work, try just searching CCO for NBAR
