DHash is designed as a block store and can certainly
store short values like "adrian" or "jo".  You should
be able to use devel/type_tests.C as a guide to how to
store blocks using the dhashclient interface.  (Also check
dhash/dhashclient.h that has a few comments in the public
interface.)

You may want to use NOAUTH blocks, so that the DHash key will
be the SHA-1 of "adrian"; if you use CONTENTHASH blocks,
the DHash key would be the SHA-1 of "ad".

We're working on cooking up a python interface that should
make it easier to write DHash applications but that probably
won't be releasable for a few weeks.
