Continuous Pre-rendering?

Here's a feature I'd REALLY like to see added to Vegas 5.0...

Real-time previews are a wonderful feature of Vegas, but once I start adding a few effects I frequently get a playback rate of maybe 4 or 5 fps... so I'll often have to "selectively pre-render" a section to see what it REALLY looks like. Which is fine, I guess. But then I think about all those wasted computer cycles, when I'm scrolling through the media bin or scrolling through the timeline or adjusting the volume on a clip... where I'm probably using 5% of the CPU's available power. Couldn't that power be put to use a better way -- as in, continually, constantly pre-rendering the project?

Hard drive space is so cheap now, I've seen 80gb drives go for $20 after rebates. An entire hour-long project (in DV, which is what probably 99.95% of Vegas users are editing in) takes up only 11gb. So you could set aside 11gb for an hour's worth of pre-render space. So whenever Vegas detects an idle moment, it could swap over and selectively pre-render a frame or two or ten or however many it can. Automatically. Just like how it saves the project for you automatically, in the background, only now it starts pre-rendering for you. So if you step away from your desk for 10 minutes, when you come back you might find that your entire project has been pre-rendered for you, and instead of getting 4 or 5 fps, you'd get a full 29.97 fps playback, even on complicated effects! If you change something, sure it'll lose that pre-render, but only until it detects idle time on the computer, at which point in the background it'd start pre-rendering for you again.

Could be a huge time-saver and a major productivity booster. What about it, Sony? Can it be done?

I don't know if it's doable with the Vegas architecture or not, I'd assume it is. This is how Liquid works, and it HAS led to instability in the application. That's the bigger fear for me. But it's a good point, one that's been thought out by Pinnacle and Blade. And both those apps are unstable. I'll trade stability for speed any day.
I'm not discounting your desire at all, it would certainly be a great use of the CPU.
