That's the one from Barco. Christie has the Solaria One. NEC has NC900. All three are based on the new(ish) "compact" 3 chip DLP 0.69" platform for screens under 30'. NEC is cheapest at I think $30k MSRP (source
) Christie and Barco are more. My understanding is the NEC is fairly bare bones to compete on price, while Barco & Christie have more features which help to justify their higher price (to some people).
I think you can rip movies to the integrated media server, but still looking into that - I don't know. It's intended to hold movie theater movies (DCP). Most have HDMI inputs to display what they call "alternative content" which would be something like Bluray. I don't think 3D is ready to go - would have to buy a system from Dolby, RealD, or one of the others. There are 4 or 5 different 3D systems out there, each with tradeoffs. I'm not sure if the commercial 3D systems work with 3D Bluray content by default (need to find that out as well). I know people in the DCI forum have got their projectors to work with 3D Bluray using a collection of devices, but part of the value from the compact projectors is they have the server built in. Maybe that will turn out to be wasted for what we would mainly use it for (Bluray). Not sure if Ghostbusting works for Bluray either... I don't think so.
Other downsides are they run on 220v, are hot, noisy, big, heavy, and some have special cooling requirements (like a powered fan to vent the heat outside, although I think they have adapters if you want to deal with the heat in-room). The rated CR is also terrible compared to what is "available" in consumer space. I put that in quotes because many argue that the CR spec is exaggerated in consumer space and far more importance placed on it than really matters. I've never been bothered by black level at the movies, but have at home with projectors with much higher rated CR so maybe there is something too it. But then there have been comments by a few people like Art & Colmachine that have seen DCI in a HT setting and said CR and low light performance was lacking. You also have people dumping their half their light with iris mods to get better CR. Maybe because they didn't need that much light in the first place and its a good way to dim (pick up some extra CR in the process vs ND filter) -or- maybe low light performance really is bad enough with Bluray content that the trade off is worth it. Not sure if dropping half the light on a 9,000 lumen projector to get better CR makes sense... all things considered, might just go with a DPI since they appear to take a similar approach out of the box.
The main real world benefit to DCI, for me, is the ability to physically align the DMDs to better/perfect convergence. It's a feature on Barco and most of the Chisties - not sure about the others. I've seen claims that Sim2 and others could do it, but never heard of it actually being done. It's not a published feature on any consumer projector, but it is on most DCI projectors and seems to be done standard with a good install. Have you ever seen red/blue fringing on text at the movies? I haven't but every projector I have owned has had it to a certain extent. Art's projector is the best I've ever seen. I don't know if he got lucky or a cherry picked machine, but for me it would be a dice role. Too much money to just hope for the best.
So, not suggesting you run out and buy one. Just maybe something to consider in your search.
