I would be willing to bet a rather large amount of cash that I could get 3D from a computer to run on a single 20 year old front projection CRT as long as it can handle a decent input scanrate.

In fact about a decade ago I used a Sony G70 CRT front projector (a fairly high-end model manufactured in 1998) and was able to run 120 Hz refresh rate from a PC for playing 3D games (using an Nvidia video card and LCD shutter glasses). The 3D effect was quite good but the image was rather dim on my 100" screen.
However, if you really want to use the home theater for viewing movies and the new 3D TV channels that are coming over the next year (ESPN 3D, Discovery Channel 3D, etc.) then there is simply no 3D projector yet available that includes the required video processing and HDMI 1.4a input. The first such projectors will be arriving in the second half of 2010 from companies such as LG (prototype shown at CES in Jan. 2010) and from JVC (demo expected at CEDIA in Sept. 2010). Surely there will be several manufacturers with 1080p 3D DLP models later this year. All of the current DLP 3D projectors are 720p and are intended to be using a PC as the source for the 3D video, games, presentation graphics. These projectors do not have the required HDMI 1.4a input nor the decoding for the various 3D video formats, including those used for Blu-ray 3D. However, it will be possible within a few months to configure a PC with an nVidia graphics card and a upcoming upgrade for PowerDVD 10, to play 3D blu-rays on a PC and output the video in 120 Hz sequental mode, that will work with some of the existing 3D ready displays. But, this still doesn't help with getting 3D video from cable TV or Directv.
