Dave,

Enclosed is the pointer to a paper I mentioned during the conference
call today that was published recently which describes a Replica
Registration Service (RRS).  I want to draw your attention to section 4
that briefly describes how this service fits as one of three services
that can be used by a Replica Management Service (RMS).  I think this
fits your concept of "composable services".

Also,

I want to mention some desired functionality when using storage services

as parts of other services (I mentioned that briefly during the call).

These include:

1) there needs to be a way to requesting to reserve storage space, and
passing that information to the transfer service.
2) there needs to be a way of passing to the storage service the desire
to keep files in the storage space for some lifetime, and releasing the
lifetime commitment when done.  This does not necessarily imply removing
the files.
