get the private key for change addresses Is it possible to get the private keys for change addresses that get generated?

I was wondering if there is a way to auto export that, do the clients make the change addresses or does another mechanism in the network make them?
I think you can do this by using the bitcoind JSON-RPC interface. 

The following links should be helpful:

Identify the change address by looking at the transaction in question and then use "dumpprivkey ".

My understanding is that bitcoind is creating the change address every time you do a transaction where the change is greater than 0.0.
