I'm with Pred on this one.
I was looking at nero and such the other night looking to burn VCD's. Nero is supposed to suport multiple drives at once. So I would make an ISO image of the master disk, then burn to 3 Lite on 52x 24x 52x burners at once. If you have more than one system, then maybe use 6 Burners. So forth,
For safety, I would not write at full speed. I would stay at least one or two speeds below the disks rated speed. Less chance for errors. Do you want to listen to 2,000 disks of the same thing to see if they hiss or pop, snapple, crack? I have done some High Speed copies from the ISO file on the hardrive, half way through the pops and skips start. Although I don't have trouble with high speed data disks!
Still, having to swap out 2,000 disks manually is gonna be a killer!
How you gonna label and package them? You plan to do this often??
Neato labels are expensive! You can silk screen them if the design isn't too complecated! Maybe stay with a simple one color design. Build out your own setup and frames. Be sure you can't get any ink on the data side of the disk or scratches. The silk screen ink is like a very thick paint, you squegee it through the screen. Not hard to make the screen and frames.
I take it you plan to profit from this venture
One thing you might keep in mind on hardware. Buy the new lite-on recorders you need, (if you have the bucks), burn the disks, if you no longer need the drives and they still work good (not fried) then sell them used. You could get alot of your money back on the drives.
If you buy new drives and you fry a couple doing a massive burn like this, then RMA them. Sell the ones you get back. Or if you can exchange them at the store for new ones do that, like wallmart or bestbuy drives.
Or if you are gonna get it all done in 30 days, buy the drives at Bestbuy or wallmart. They have a 30 day return or longer

I didn't say this!
Get the drives, burn this disks, return the drives for refund, no expense for hardware cept gas to get to bestbuy/wallmart twice. once to buy, once to return
Personally I would not do that thing, although some people might, it is an option if you must, save the receipts!!!.
Anyway I thought about doing the same thing before. So if you need any help I already put alot of thought into this.
If they get up to wanting 10,000 at one time, you can have them stamped professionally, silk screened, case inserts printed, packed into jewel cases, shrink wrapped and ready to send to WALLMART or wherever for $1.25 per disk last I looked. (About 2 yrs ago.) Shipping extra!
Remember the above trivia next time you pay $15 or more for a new CD at wallmart!
Send a donation to the big record labels, they aren't making any money, boo hoo, yea right!
