Ah, It's been done.  Several of the larger TV manufacturers, Sony,
Hitatchi, etc. have models that will buffer the incoming video to produce
60hz non-interlaced TV from standard NTSC transmissions.  And this is
full color.  I've also heard that somebodys chips will 'interpolate' 
either inbetween lines, or when movement occurs, I'm not sure whitch.
Details on that are a little sketchy I think.

Now the big question is, is are these models actually out at all yet, or
promised RSN, or just out in Japan, not yet in the US or what, and what
are the model numbers and $$$ figures?
