I'm afraid I currently find the jClouds code base pretty much impenetrable (I haven't had a lot of experience with dependency injection) so I couldn't be sure from what I've ascertained so far. The RunningInstanceToNodeMetadata code is really useful to help me understand what's going on.

Fair enough - again, I'm currently at a stage of spiking jClouds to understand it better, but would happily do some work to get some features into the code :) > - Secondly: I'm doing buildApi(classOf[AWSEC2Client]) on the >> ContextBuilder to get the vendor specific API - however AWSEC2Client is >> deprecated.
