+* would be nice to have a way to see what computations are used by a
+ compute remote for a file. Put it in `whereis` output? But it's not an
+ url. Maybe a separate command? That would also allow querying for eg,
+ what files are inputs for another file.
+
+* "getting input from <file>" message uses the original filename,
+ but that file might have been renamed. Would be more clear to use
+ whatever file in the tree currently points to the key it's getting
+ (what if there is not one?)

* allow git-annex enableremote with program= explicitly specified,
without checking annex.security.allowed-compute-programs
