Answering this question: How do I import/export KML to ArcGIS Desktop? raised another one. There are loads of tools to import/export kml/kmz. Are there tools available for native viewing of KML in ArcMap?
I'm curious if anyone has built a custom featurelayer(s) that reads kml, similar to the way ZigGIS uses PostGIS as a data source.
Or maybe something like inmemoryworkspacefactory, which probably doesn't count as native, but would have some advantages:

Interoperability Extension will read KML/KMZ natively - http://www.esri.com/software/arcgis/extensions/datainteroperability/index.html (it is basically FME in ESRI clothing) - at extra cost of course - ESRI should make it standard with the software.
