Ask HN: License fee for BDB (Berkeley Database)

[psaccounts]

Does anyone know how much Oracle charges for using BDB (Berkeley Database) in a dual-licensed open-source+commercial application?

While Tokyo Cabinet (http://1978th.net/tokyocabinet) provides a similar key-value DB like BDB, it lacks some features like replication, custom recovery logs and checkpointing which BDB has. Oracle on its part has made it very difficult to determine BDB licensing (we have to go through a sales rep and it is taking way too long).
