Affordable HD storing/playback server 4 blu discs

What are my options - if any - for being able to copy my Bluray disc collection (and Netflix rentals???) to a media hard drive storage server? Can any of the Kaleidascape units copy, playback and store - bit for bit - my discs, without the disc having to be present after it's stored? I'd like to plan for the future, when there aren't any bludisc players, period,and be able to sell off my disc collection. Can HT PC's do anyting like this, and playback bit for bit of the original?
I'd of course like the most cost effective route, but would explore all the possibilities? Or am I resigned to having to keep my bluray discs to get the original quality and HD audio/video on the source?
