hi Dan,
i think you have pinpointed the gist of the point i tried to make:
choosing right tool to the task.
it is just too often that one approach (like using lease, using tuple
spaces, using SOAP, using REST, etc etc) is presented as a solution to
all problems and applied where it should not be. in the end there are
many types of distributed systems and they require different approaches
and that is where web services (SOAP or REST) are so useful as the
lowest common denominator but higher level of abstractions are needed
too just not for everything (requiring everything to support leases is
not realistic or even possible ...)
thanks,
alek
