[Swift-devel] [Bug 76] disable intermediate stageout of data

[Ben Clifford]

I don't think that's true.

If data files are labelled with URIs rather than 
paths-relative-to-submit-directory, then those URIs are understandable 
without a VDC-as-entity.

You don't need a separate VDC to tell you how to get at myfile here:

  file myfile <"gsiftp://terminable.ci.uchicago.edu/scratch/foo/">;

The 'data file pointer store' exists already - its the hierarchical 
namespace that is rooted in IANA's management of the URI and DNS space, 
continues to UC's management of DNS space and then down to my management 
of terminable's filesystem space and then down to whoever owns the foo 
directory.
