Compare 2 PDFs programmatically with Acrobat XI SDK

Is there a way to compare 2 PDFs programmatically with Acrobat XI SDK? I have read elsewhere in these forums that it was possible in Acrobat 8 using C/C++ methods. If it is not possible with Acrobat XI, can we still use those C/C++ APIs from Acrobat 8 although the Desktop version running is Acrobat XI?

Is an API feature for Compare PDFs in Acrobat XI in the feature list/roadmap?

Any technical details and links to information/references is greatly appreciated.

Thanks very much for your response, really appreciate your help.
