In the real world there is a specific definition for a RTOS, one which does not have "soft" RTOS and "hard" RTOS. BeOS was not a RTOS at any stage. Just because it had good response times and was designed with multimedia in mind does not make it a RTOS. I haven't read anything about intent being a RTOS either, VP not withstanding.
QNX is a RTOS but, ironically, it is not as good at multimedia as BeOS was (is). In fact it would be fair to say that being a RTOS is not an essential prerequisite for a desktop OS. Of course, QNX is not really designed as a desktop OS and that is not QSSL's core business.
Which gets us back to TAO and intent. I have to admit to getting a bit tired of "AmigaOS will have this, AmigaOS will have that.". I know both Amiga and Hyperion have said AmigaDE will be incorporated into AOS4.2, but crucially we have heard no such statements from TAO, and yet it is TAO who would have to do the porting, because I haven't heard anything to indicate that Amiga Inc have any license to do any porting themselves. TAO have shot Amiga Inc's "plans" out of both barrels before (anyone remember how the new AmigaOS would be built on top of TAO technology?), and so far they have demonstrated that they do nothing without it falling soundly within their business and financial plans. I don't see how supporting an obscure desktop OS with a maximum user base of a few thousand users falls within TAO's business plan, but maybe someone knows something I don't, eh?

Essentially, Bill McEwen has always said "don't believe it unless you see it on our site". Well, WRT TAO technology I tend to apply a similar rule: "don't believe it until TAO have confirmed it."
