I like the idea of this module, but it's totally unscalable as it is.

I entered in a 12 hour road trip, and it created 3000 entries in the gmap_direx_route_polyline table with each of the latitude and longitude points.

I was hoping to extend this module to build a rideboard module that queried points along the route to see if potential ride-sharers were along the route. Obviously, this module would be perfect for that, but it's unworkable given the fact that 50 users would result in 150,000 records.

So, any plans to work around this problem? Clearly, there is a need for a module such as this.
