We are building a process which will allow users to submit a table of GPS data to update our central repository for all GPS data. Let's say that the target is simply a SQL data table. At first I thought about trying to accomplish this with an SQL INSERT wrapped in a Python script (exposed a GP tool). However, a colleague suggested that we somehow just get the table to the server and let integration services handle the Insert/append to the SQL table.

My question is then, how to create a simple file retrieval service? I'm comfortable with the Python/GP service aspect of ArcGIS server. Basically it would be just the user submitting a table and placing it in a known location on the server.

EDIT: I should add i'm not looking to upload a file from HTTP location; it must allow access to 'local' files on the user's system.
