I can see the use of A2000s in schools as a very valuable history lesson in computing, and how the Amiga was first to offer capabilities now taken for granted, but unless you're putting together 10-12 fully decked-out, 060 OS3.9 CyberVision/PIV video, Ethernet capable A2000s, or A 1200T PPC/Mediator system, I don't really see the benefits of introducing them to the Amiga as a modern system. These kids have probably got WinXP boxes or iMacs at home, not to mention games consoles. I don't think they'll see the appeal that the rest of us have found.
That being said, I do wish you luck in your endeavors. These kids will at least grow up knowing what an Amiga is. Most people in my generation don't.
