  1. Hi Ura, if I can understand, going forward ViPR Controller will be based on CoprHD project which is the open source stream and it will also be based on the commercial stream. I don't remember seeing a product released/available in both commercial as well in the open source stream. So wondering if the strategy to go in both direction is for a short term? If you could shed some light in that area, that would be great.


    1. Check out this page that talks about redhat, fedora and CentOS. I think this is sort of what we're looking to do with CoprHD.


  2. Hello everyone:

    Please don't take my opinion on what I thought to be a good example to the question two months ago as gospel. I assure you, it is not. I was only using the redhat case as an example of a project that has both a commercial and an open source release. I was not making a statement of how things will actually run in CoprHD.

    Thank you,
