I would like an improved description than this; ideally one
should be able to compare the description of 'dsh' and 'pdsh' and
see how they are different.
I'll try and update dsh description.
The major difference between the two implementation seems to be
(from your description):
o pdsh includes rsh itself, while dsh does not
o pdsh tries to keep fixed amount of connections at the same time
for parallel connection, dsh does not care; dsh uses a
fan-out mechanism for large-scale job submission.
