Does anyone know if it's possible (lisp, .Net) to automate the location and values of SETNETWORKCATALOG variable for Civil 3D?

This might be second post\thread, but does anyone know or recommend any resources to easily setup multiple CAD Standards for Civil 3D?

Outside of the normal Civil 3D template files and profile (*.arg) I was looking for a way to put some sort of ini file in the project working folder and have code read through that and set paths for certain support files. (Pipe Catalog location, plotter, symbols, other support files) I have 4 Client's standards (Civil 3D) that all need to be implemented in the next 4 weeks. Thought I could do something with acaddoc.lsp or acad.lsp but Pipe catalog location, among other settings, are not configurable here.
