I feel pretty qualified to comment on all of this. I did Cornell's FALCON program for a year, and now I am in Japan. I have been here for 9 months now.
The textbook we used was called JSL: Japanese the Spoken Language, and it was absolutely awesome. The ENTIRE thing is based on conversation memorization and drill sentences that pertain to real-life social situations that you will encounter in Japan.
There is audio and video available for the textbook, and all of the examples are proper, frequently heard Japanese, spoken/acted by real native Japanese speakers.
It worked. Really well. (One drawback that many people mention is the fact that it uses romanji, but if we are talking about learning to speak and not so much about the writing yet, then this is the way to go.)
HOWEVER, there are drawbacks to this method.
1. real Japanese is not romanji. (Although this can be solved by picking up supplementary reading books like JWL, or Reading Japanese).
2. lack of vocabulary
3. KANJI!! (and how it doesn't stick in your brain!!)
2 and 3 are the real problems. 3 is kind of solved with Remembering the Kanji. I have learned new words because of RTK, which I think is so cool. But the problem with RTK is that it's not just a kanji problem. It's also a vocabulary problem.
And I think the way to get around this is to practice reading to Japanese audio (without studying the Kanji). You would have 1 or more translations of the text (less literal vs. more literal depending on your Level) in addition to the real Japanese text.
This is where I think some sort of sentence reading exercise on the web would be invaluable.
We'd get the new words, and we get to see how they're used naturally.
If you were to make something primitive.. say of the first chapter of Reading Japanese or... of some newspaper articles using certain kanji... something that would review not just vocabulary but vocabulary in context (in Laettner fashion, or something cool like that), then you could have a smash hit on your hands. Books are annoying because you have to review them and know where to review and so on. It'd be much easier to do this stuff on software.
People in the educational market suck at making software. やってみたら?

. At this stage you're just trying to beat your brain into doing a little active recall to start the memory chain reaction.
