I know people that have done this, and it works to some extent. =) The
problem is that without a controller to track the sun, you only get the
reflections for part of the day, and the intensity can also burn your
plants to a crisp (and leave very noticeable faded streaks across your
furniture/decor if you're not careful!).
But fully automated active daylighting kind of makes me drool a little.

I spoke once to an engineer working with a system very similar to the one
pictured above that quoted me around $24,000 for a similar fully automated
system (with a much cheaper lens than what is pictured, and that was just
for the parts I'd need for my single story home to pipe enough light via
fiber-obtics to fully daylight ONE room in the basement).
I know the prices have come down some, but at the time I figured if it
would costs as much as the addition of a modest solarium, I'd take the sun
room!
To catch up with the posts I never replied to-- those collection photos
Sara and David posted were fantastic. I'm definitely going to try moving
some of my plants a little farther away from my windows to see how things
go. I had a decent sized kerii in a "dark" window for some time, but it
paled up and never bloomed, so I moved it back into a well-lit exposure.
Time to play species roulette?
Also, in reply to someone else's question regarding artificial lights,
I've had bella, lacunosa, and several types of carnosa cuttings in my dart
frog terrariums for a little test (over a month for the carnosa), and
they're all putting off massive amounts of roots (due to the humidity I
suppose?) and the carnosa cuttings are already sending off new growth.
They're all between 6-18" away from 128 watts of shop lights (two T8 $10
double bulb fixtures from home depot). I try to go natural/green where I
can, but the frogs stay in the poorly-lit basement so there's no chance of
overheating in the summer, so it was a great opportunity for some hobby
overlap.

Thank you Sara, I have just begun with the hoyas in ernest and did not know all of this. I guess I have a lot to learn. Thank you, Billy
