Assuming that the administrator has privilages on both
machines, how does this differ from simply executing a
resident monitoring program on the observed machine
that does exactly what the agent would do.  Then it
phones home with the answers?

Haha  .. not sure at all!  There are more damned names
and ancronymes crawling all over this stuff than I can
absorb.  I certainly hope that parts, if not all, of
what we are working through has been though of enough
to give us guidance.  If thinking about 'Mobil Agents'
casts a light on our design problem, excellant!

So far, just within this project.  I presume there are
areas of research that encompass what we are thinking
about.  That would be most helpful.

Yes.  We plan to prototype the system in perl.  But we
do not anticipate perl as the final working

That doesn't sound inconsistant at all with what we
are thinking about.  Do you see any basic archectural
problems in the docs so far in designing all of this?
