We are also considering an alternative backend which is friendlier to javascript.  Basically a zip file with a JSON index defining the NeXus structure and storing the small fields, plus binary files for large arrays.  With no HDF dependency we can do browser viewing and plotting without users having to install anything, and without a round trip to the server.  We have some prototype python tools to convert to and from hdf5, but haven’t had time to formalize the definition and send it to the committee.
