Oh, he'll want to fix some of the inherited bugs:

https://github.com/john-connor/vanillacoin/blob/51c6960b2a14ffbf67af19aefac6291768e1ffbc/include/coin/address_manager.hpp#L120

corresponds to

https://github.com/bitcoin/bitcoin/blob/0.9/src/addrman.cpp#L12

but not

https://github.com/bitcoin/bitcoin/blob/0.10/src/addrman.cpp#L13

I presume for someone who is apparently smarter than the entire Bitcoin development team put together, understanding why and updating the code accordingly will be trivial.
