IP GeoIntelligence - Additional data elements

For those customers which use IP GeoIntelligence and the Digitial Envoy monthly feed, would it be possible to expand upon the dimensions available?  Checking the Digitial Envoy website, there is a new indicator (for identifying if an ip address is residential or buisnes) available with their feed and this is something our marketing folks are very interested in.  Also, would zip+4 be available versus just the 5 digit zip?
