One of which was the goal of having separate code bases for the two projects in itself, so we could test both, and the RFCs they were based on, for interoperability, and regression (the NSD release cycle includes a suite of tests, amongst which quite a few that use ldns) Unbound does use and rely on ldns, and ldns has had quite a few improvements from unbounds' use of it, which are slated for release. But there still is a lot of overlap in functionality both their code bases. The reason for this is partly the same as the one above, but mostly that the 'non-functional' requirements are quite different: unbound is meant to be 'lean and mean', more efficient than a hungry school of piranha's, and optimized and designed purely for resolving and validating, while ldns is a general library (and by now, a general dns toolkit), where speed and efficiency are less important than general functionality and ease of use for developers. Unbound and NSD are, as said before, two different beasts, who happen to be able to talk to each other.
