I had a feeling that might be the case. Apple is so paranoid about apps sneaking in undesirable (or unwanted by Apple) features, that software for controlling third party hardware takes forever to gain approval. I think they need to create a separate department / segment of the Developer Portal, exclusively for apps designed to control vendor’s hardware. That would at least allow,them to maintain a core group of software testers / evaluators who are more familiar with these types of apps.
