Am I correct in saying that if that is the case, no matter what the optical disc format, kaleidescape will always be able to handle it with new readers
Well, no, it's not correct to say that no matter what the format
, Kaleidescape can do it. In theory, a format could come along whose licensing restrictions preclude what Kaleidescape is doing with DVD. In fact, the folks at CSS have their knickers all bunched over what Kaleidescape is doing now with standard DVD, and have sued them over it. The lawsuit's not likely to go anywhere, because Kaleidscape took great pains to comply with their CSS license. But what is important is that Kaleidescape will put forward the same effort in the future to remain legal with future formats as well; it would be suicidal for them to do otherwise.
So, onto Blu-Ray and HD-DVD. Poindexter is right, both of the new HD disc formats support mandatory managed copy (MMC), which is good news. But as always, the devil is in the details, and there are two relevant ones here. First of all, the studios are free to set the cost for managed copies. If they decide to be insane, they could charge more than the MSRP of the disc itself---i.e., they could price it out of reach for any reasonable consumer.
Secondly, the managed copy has to be transferred to a system whose security measures have been approved by the AACS consortium. I imagine
that a sufficiently product-neutral storage format will be approved by AACS in short order, and Kaleidescape will be able to take advantage of that. In case that does not happen, Kaleidescape will have to float its own security model by AACS. Maybe they're already doing that, I don't know. Certainly, they have a very secure system, and except for possible anticompetitive reasons I can't see AACS turning them down.
In summary, I think we all have good reason to be optimistic that Kaleidescape will be able to support these new formats, eventually. But it is by no means a surety; and even if it comes, it may not be cheap. If you decide that you must
have assurances that Kaleidescape will support these new formats, you're going to have to wait for the company to provide those assurances themselves. We can speculate all we want but only they can give a definitive answer. And I doubt they will be able to do so at least for a little while, until the AACS spec settles down.
On the other hand, who's to say that Kaleidescape needs
HD-DVD or Blu-Ray support? Their system is ideally designed for online distribution of content. They certainly have the security measures in place. So who knows, maybe one day the fears about these new disc formats will be irrelevant, because the studios will have cut deals with the studios to do things their own way.
