Wow. This sounds like a TERRIBLE idea. ICANN is going to allow tiered pricing for .biz, .info, and .org domains. This means that a domain name registrar can set individual prices for different domains. They have to give 6 months' notice before raising prices, during which the domain owner can pre-pay up to 10 years at the old price.
This means that the registrar for, say, eff.org, if they didn't like them, could decide to increase fees to $1 billion a year. Then the EFF would be forced to pre-pay 10 years... and then who knows what will happen in 10 years?
This doesn't apply to .com and .net domains. Yet. I'm curious to see how this pans out, but this is sounding a lot like the net neutrality debate.
