Review Comment:
Not too tricky, I hope :) WDYT about mapping base table URIs to credentials?
The server could return this mapping in response to the client's request for
credentials, then the client would choose the appropriate credential for each
file it needs to access.
If the client provided some more information about the time of operation it
needs to perform (e.g. read the latest snapshot or append new files to the
latest snapshot) the server should be able to return a fairly narrow set (1 in
most cases) of credentials.
