Does it with both maps - can't use Google because the tour maps require a key, and Google no longer requires keys.
google does no longer give keyes for the flash api. the current google api is java based and that is in ptp or better in the mapsplugin inside ptp not supported currently.
the ptp "google maps plugin" is not equal with the krpoano based google maps plugin.
In fact the panotour maps plugin is one plugin which supports different map provider, google (if a google flash api key is given), OSM (no key to enter), Bing maps (one bing maps api key can be used for different domains even when the key is only registered for one domain...) and if bing maps is enabled and no key is entered than the OSM is used automatically instead.
