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. -Jason -- [EMAIL PROTECTED] SDF Public Access UNIX System - http://sdf.lonestar.org _______________________________________________ pspp-dev mailing list pspp-dev@gnu.org http://lists.gnu.org/mailman/listinfo/pspp-dev
