No, i have not seen a 1080p (by this i am assuming you simply mean a large TFT panel with 1920*1080 native resolution. I am sure it is very impressive indeed and i agree that LCD technology has come a long way. It is still not passable as an alternative to a quality CRT display though, it may well overtake someday (although obviously there will always be scaling issues), but it is not that day yet. You must also consider the price of the decent digital displays, they are well into the thousands and i for one am not willing to pay that for something as menial as a display when there is a cheap superb form of display available in the form of a CRT projector.
Admittidly there are only a handful of large CRT displays capable of 1920*1080, but we find the same with digital. Where we could compare is 1280*720, now here we find that almost every CRT produced within the last 5 years with high resolution video in mind is capoable of it, easily, and more, with the ability to shut off all light producing excellent contrast levels. There is also no issue with scaling.
Theres just no contest at the moment. I dont see what HDCP has to do with anything also, last time i looked component video was quite capable of the bandwidth required for resolutions surpassing 1080p, and all devices i have seen have been able to output in this format, or a format which could be converted.
edit: By the way i am not trying to critisize you, i just think that perhaps you have not considered all your options when it comes to your projected display. With that lovely dedicated room of yours it would make for a much better experience if you ceiling mounted a CRT
If you havent properly demoed one, then do, really please consider it, i bet you'll buy one!
