+Still working on removing kvm from netstat. Currently most interface information can be retrieved without any references to internal data structures. Interface information is now being obtained through sysctl with the {CTL_NET, PF_ROUTE, 0, 0, NET_RT_IFLIST} mib. However, two pieces of into that is not readily available is:
+  * Watchdog timer
+  * Per address statistics (as provided by struct if_data)
+//July 11<sup>th</sup>//
+At this point all interface information is obtained using sysctl. Other parts of netstat that already use either sysctl or ioctl include:
+  * IPv4 Multicast routing informaiton
+  * Mbuf info However, IPv6 multicast routing, IPsec and Apple Talk information all rely on kvm at this point.
