1  Well structured code, with extendible sane architecture.
2  Server, which has analysis in cache for N seconds and will
   answer via socket.
3  Configuration file for server.
4  State file, where different ranges, shared networks etc have
   unique identifiers (needed for graphs).
5  Support for snmp and munin protocols.
6  SNMP traps when limits get exceeded.
7  Some clever check_dhcpd_pools binary for Nagios & other
   monitoring software.

8  Super server support, which will collect analysis from other
   dhcpd-pool servers.
9  Nice http view interface on super server, much can be copied
   from http://piwik.org/
10 IPv6 support.
11 And some other things perhaps...

When items 1-7 are done v3 can be released. To support rewrite
there should be a design document with nice blue print, which is
a web page.
