It seems, according to the document on OTN - Oracle FAQ: NAVTEQ Digital Map Data for Oracle and to OTN Forum post - Oracle & Navteq FAQ & Countries boundaries, that with Oracle Database 11g will be shipped countries boundary data provided by Navteq. Also, the same map data will be available on OTN for download.
Great! I think, it will be even more easier than now, for non-GIS people to start building BI applications with included Oracle Spatial technology functionality. Developer will have everything out of the box - from data to tools.
