12. The processor-readable medium of claim 10 , further comprising code to: filter the new version of the design document for relevant information.
10. A processor-readable medium storing code representing instructions that when executed by a processor cause the processor to perform a process, the code comprising code to: store a past version of a design document sent from a computer associated with a first entity within a memory of a computer associated with a second entity; store a new version of the design document sent from the computer associated with the first entity, the new version of the design document being sent from the computer associated with the first entity after the past version of the design document was sent; store a dictionary within the memory of the computer associated with the second entity, contents of the dictionary being accessible to the second entity and not accessible to the first entity; and set the past version of the design document to the new version of the design document when the new version of the design document and the past version of the design document differ, and after the past version of the design document is set to the new version of the design document, correct, at the computer associated with the second entity, the data that has changed between the past version of the design document and new version of the design document using the dictionary to produce a new design document with data-to-use, the new version of the design document with data-to-use being accessible to the second entity and not accessible to the first entity.
