We want to release 240/4 as a solution for those organizations that are in a position to control enough variables to make it useful. For those organizations, 240/4 space could buy a LOT of time, maybe even years.
If this block was to be released to an RIR, who could possibly have a use for it? You can control your own variables, but if I'm an ISP/customer, I'm going to find an address allocation that leaves 99% of the Internet as a whole unreachable as pretty useless. I might was well just use RFC1918 space. Asking the whole internet to support 240/4 is going to tie up valuable resources that would be far better off working on IPv6. Keep in mind that it's not just software patches. Software vendors don't do stuff for free. I doubt ISPs are going to pay huge amounts of money to support a peer crazy enough to try this. And until tested, there is no guarantee that hardware based routing platforms (your PFCs, etc) can route Class E addresses as if they're unicast. Just my .02 though.... Chuck
