This is like a really unique fundraising model for a nonprofit. I think I'm the only one who could credibly say "give my your old IP addresses, I'll sell them, use the proceeds for charity (buying ISO standards!), you'll get a tax deduction." I'm imagining there's probably some pools of legacy addresses out there and I'll bet you money that I might even know the registrants personally. I like this idea very much.
@carlmalamud Interesting idea! I think I might be able to credibly do with some .edu colleagues as well. However, are you going to be disappointed if I take your idea to selfishly help fund another non-profit, one I'm involved in? Or maybe we could share the proceeds if I have your backing/help and I can facilitate a legacy donation?
