Basically, what is required is a port socket to allow URL access to Google Maps / Earth, GIS, et al.
Recently I set-up a Filemaker10 property database that not only ports to Google Maps,
but to all the county GIS, Tax maps, Tax documents, and my server files.
Each Property has the location map via Google, the Aerial Image & Parcel Boundary via GIS ,
the Tax Parcels Zoning map, Tax Info, and links to CAD files.
All the info & images can be imported into VW via scripts.
Not ideal but doable.
