To your first question--it appears Skype has ported their software over... at least, I would THINK it was ported, not rewritten from scratch or treated like a whole new port. I thought Harmattan was supposed to be this in-between abomination that mixes elements of Maemo with MeeGo so that developers can migrate from Maemo to MeeGo more easily... and yet, this happened. Your latter question is the better one to ask--is there anything actively preventing Skype from porting over easily? Why didn't it support the camera already? Is there some kind of lack of hardware support or crippling or something? That really doesn't address the COMPLETE lack of camera support--especially if Maemo had already supported it... assuming this OS is supposed to be compatible and easy to port Maemo apps from. How does releasing Skype on a previous OS version make this irrelevant?
