I don't know if the following comment is relevant to this phase, but
just in case: sometimes users have client/server versions of SAS or
SPSS or other statistical software.  They use a local gui as a client,
which sends computational requests, usually those involving a large
data set, to a server which runs only the backend and has access to
the data. I thought this consideration might be relevant to any socket
v. pipe questions.
