Comment (by tomek):

 Here are initial the steps that need to be completed. Marcin and I will do
 detailed code review in the next couple days:

 Issues:
 0. The code should be based on latest master from Kea repo (see
 http://bind10.isc.org/wiki/GitGuidelines)
 1. subnet-id needs to be passed between v4 and v6.
 2. open one socket and use it, not open/close one per packet.
 3. need unit-tests.
 4. we need configuration (DHCPv4 only, DHCPv6 only, DHCPv4o6). The default
 for 4o6 should be disabled, so it will work only if administrator
 explicitly enables it.
 5. receive6to4/4to6 should be generic v4-v6 communication (Marcin/Tomek
 will take care of this)
 6. Update documentation: User's guide and developer's guide. This is
 really minor thing, so we can deal with it last.
