1)I like the spirit of title but find the contrast in tense jarring --
Metacomputing and Supercomputer -- I was thinking of something like
Metacomputing: Harnessing Informal Supercomputers
2) End of first paragraph of 1.1.1 -- add:
  However linking of self contained applications is of growing
  importance in science (multidisciplinary applications) and industry
  (linking different components of an organization together).
3) Somewhere emphasize that metacomputing encompasses
a) Seamless access
b) "Parameter" studies (embarassingly parallel ala FAFNER)
c) Linkage of Scientific instruments, analysis system, archival
storage, visualization (4 way metacomputing)
d) As well as general complex linkage of N components
You have much of this already. Essentially all successes are the modest
a) b) c)
4)FAFNER won an award not the award at SC95
5)Change "supercomputing 95 to SC95 under IWAY second paragraph
6) know is known in paragraph introducing CRB
7)extend is extended in paragraph ending Nexus.
8)1.3.1 add as bullet
Provides Appropriate synchronization and component program linkage
9)Tell people what LDAP is. Essentially nobody knows
10) Give examples of Legion objects early on to explain concept
11) Legion says it is "emacs" of metacomputing as so customizable
12) Functionality matrix comments
Webflow uses hierarchical communication services including socket
and MPI. 
Under availability -- WebFlow is NT and UNIX
13) section 1.5. Suggest section heading look like
Arcade (ICASE and ... - P.Mehrotra)
WebFlow (NPAC@Syracuse University Furmanski Fox Haupt) etc.
14)EROPPA objective should be objective of
15)Add Nile as High Energy Physics specific CORBA metacomputer
(embarassingly parallel)
16)First sentence not really correct and irrelevant anyway. Just delete
first paragraph
17)Last sentence of acknowledgements. The should be a
18) Expand citations to include people and preferably a paper each
