I think after it goes four tiers deep it may become crazy to manage, but we shall see. That would be 121 copies in all, which will be quite impressive to distribute. After you've distributed your three sets, you can certainly make more available in whatever manner you see fit.
If you're interested in a set, send email and snail mail address via PM and I'll get you in the queue. Then, be patient as things work the rounds.
Edit: Please note whether or not you have dual-layer burning capability. The single-layer discs are the primary focus, but for those with the means to do dual-layer burns, I'm cooking up different ideas there as well.
