Blue ray decoding path is protected so it would no be possible as you describe. But if you play a BR-Rip from a computer It can be done with TriDef 3D and a set of cyan/red glasses.
Quality sucks but is possible
The only 3D that works on a non-stereoscopic display is anaglyph or something similar. What that means is that each eye is separated in the colour channels of the image and then the red-cyan glasses you wear give you the illusion os 3D. I tried it for a while and it was kinda cool but I could never get it to be successful with a client as the quality was always unreliable. The whole process leaves it all blurry and the only way to avoid too much blur is to reduce the 3D effect. At the same time, because the channels are shifted and you are using the coloured glasses you lose a lot of colour depth and accuracy.
I guess my answer may only be relevant if you want to experiment with making the stereoscopic content yourself, so if you are just looking for something to view then forget it. I do, however, highly recommend the 3DTVs that use the passive/polarised glasses, like the LG series. The prices are really good too.
