You might also take a look at the GIS capabilities that are now baked into sever DB systems. MS SQL 2008 and the newer versions of PostGres come to mind as having native support for geographic data. A lot of it will come down to figuring out your actual requirements, which seem to be rather fuzzy at the moment. But as much as possible, I'd suggest using a tool (like a GIS system or spatial-aware DB) that is more purpose-driven and hooking into it with CF. CF is a great tool for acting as the glue for disparate systems. Use the best tools for the job if you can.
