Some coins use an alternate form of blocks in their blockchain in addition to the standard form. This alternate allows blocks mined against a different coin's blockchain to be counted, allowing the coin to leverage the hash power of the other coin.
Dogecoin will be switching to using AuxPoW against Litecoin at block height 371337 (see http://redd.it/2egjqg), so it would be ideal to get this in sooner than later. Once this is supported, adding support of Namecoin should be fairly straight forward too.
