E: Referee Comments (For Author and Editor)
------------------------------

Good overall description of the Unicore framework. It might be helpful
to provide an example case study of how an application scientist uses
the various Unicore services either as initial motivation or to tie
together the practical benefits of Unicore services at the end of the
overview.
Good explanation of difficulties in using applets in th eimplementation
section. Also, I'm still shaky on security in Unicore. If it doesn't
implement GSI, how can a process act on behalf of a user? In Globus,
this is done via a proxy which contains a short-lived private key-- I
see from the UUDB description you have a mapping between certs and user
names, so is the UUDB and the NJS and TSI  considered "trusted" software
much like the Globus gatekeeper? And are all the connections between
these components secure? You might want to say something more about the
trust model that Unicore follows.
In Future plans, do you see web services palying any role in the future
of Unicore? I would be interested to know more about GRIP as well.
