Google Maps in Flex without Google Maps Flash API

Hello,

Does anyone know an alternative to embed Google Maps in a Flex application without Google Maps Flash API (because it is deprecated)?

To forgo Google Maps and use another map provider or to develop the application again with JavaScript/HTML are no options. Flex-IFrame or similar solutions (HTML iframe overlay) or a conversion to Adobe Air is not wanted.

Is there a solution available either commercial or open source to use the JavaScript SDK from Google in Flex (e.g. via ExternalInterface or Flex Ajax Bridge)? Or is there an alternative Flash SDK for Google Maps available?

Thanks!
