DM-11: Post-allocation data access on XSEDE SP resources

Executive Summary: 
A researcher needs to access his/her data on an XSEDE resource after the end of his/her allocation.
User Importance Summary: 
Most XSEDE SPs offer a grace period following the end of a user's allocation period for the user to "clean up" and archive his/her work. Research productivity is hurt if the researcher needs to learn a new set of tools and/or access credentials during this "clean up" period.
Target Communities and Sizes: 
XSEDE-allocation researchers - 10,000 < N < 100,000 XSEDE L1-L3 SPs - 10 < N < 100
