Thanks for you interest and suggestions, a couple of quick points below.

I guess I just ran out of steam on the documentation front :-)

Currently it maps integers to DWORD and anything else to REG_SZ.  The
idea of having a distinct Value class is to allow a more nuanced mapping
to be developed, but I haven't got down to the details of that yet - my
current application only requires REG_SZ.

It certainly is, using syntax like:

  HKCU.foo.bar["key"] = Value("%SYSTEMROOT%/mydir",type=REG_EXPAND_SZ)}

Putting a nameless Value() instance in the initialisation dictionary
should also work (but as you note, there's no documentation or tests for
this yet...)
