Should intermediaries be considered as an extension or part of the core
Should the application layer take care of the intermediary
business or will it be handled at the XP layer (with automatic discovery
and such)?
I would redefine a) b) c) with the following:

a) go to the machine M
b) go to the service S
The application may choose between both addressing types, then the XP
layer would "transport" it to either an intermediary, or the ultimate
recipient, which may not be known by the application.
