[ddns] "update-conflict-detection" and co-existing DHCPv4/v6 servers

I'm using DHCP and bind to do DDNS and I had to disable the
"update-conflict-detection" option to allow DHCPv4 and DHCPv6 to update
the DNS independently.
The problem is the follow : when "update-conflict-detection" is
disabled, a client can indirectly update and even delete A records by
booting on the network with the same name of a server for example.
Is there a possibility to run DHCPv4 an DHCPv6 simultaneously AND
verifying the TXT records?
Alternatively, is it possible to "lock" some records to prevent update?
Where're using DHCP 4.1.1-P1 and Bind 9.7.3 (both Debian Squeeze).
