One possibility would be to implement something like DHT's
filter_loc_subvol_key, though perhaps using child indices instead of
translator names.  Another would be a script which can manipulate
volfiles and use GFAPI to fetch a specific version of a file.  I've
written several scripts which can do the necessary volfile manipulation.
If we finally have a commitment to do something like this, actually
implementing it will be the easy part.
