How can I save previews for old projects, while burning the project to DVD?

Question

I'll admit, I haven't read the user manual cover to cover (or screen to screen for the electronic version), and haven't spent hours combing the discussions here, but I have searched for all the relevant keywords I can think of and can't find a concise answer to this question.
I get the basic idea of Vaults (I think), but haven't found much info about long term storage of projects. I'm fulltime freelance, but not super busy, and I can easily generate 100,000 images each year. I don't have the cash to be keeping all of these images in Aperture projects on external hard drives for eternity, and I'd be surprised if anyone else does. Good thing I'm not a medium format digital shooter producing 50GB each day huh?
I remember seeing a clip of a photographer 2 or 3 years ago discussing the differences between storing digital and film images. He was making the point that throwing away files you don't think you'll need again can be a mistake, citing a shot he had of Clinton and Lewinsky together, before Clinton and Lewinsky were news. "If I'd been shooting digital, that image wouldn't exist today". It was a great pic, and when that whoel scandal erupted, it made him alot of money.
So at present I'm storing every image I take in finished projects on DVD trusting that in the future I'll be looking for a shot of someone I may have shot 5, 10, 15 years ago.
I caught part of a discussion that talked about keeping the preview files for all the images (and subsequent versions) for each project. I'd love to be able to keep lo-res previews/copies of everything I've shot to date, and have them immediately accessible on my hard drive, while my full size projects are safely stored on DVD, taking up space on a bookshelf rather than on my hard drive. Loading 10 DVD's worth of projects to see what's inside them is a headache I'd like to avoid if possible, in favour of instantly checking out lo-res previews to look a shot up.
Is there an easy way to burn a completed project to DVD, but keep only the (lo res, lo size) previews on my hard drive?

yes.
maybe,...
1. you might think of making DVD backups first prior to importing the photos into Aperture. "Store Files: In their current location" once in Aperture make low rez Previews, and export finished Project.
or,

the low rez Previews will stay in Aperture but the high quality Versions will be exported onto DVDs and gone from the hard drive (if you delete the originals).
another way would be to export small about 50-70 pixel wide high quality jpegs to a folder on your Desktop and import & keep these in Aperture Library as a reference. make metadata to show where the original Project DVDs are stored and DVD filing system used.
