I think the only thing I know of that is sillier than that would be Avi Freedman’s BGP4 implementation
on a palm pilot.

For what it’s worth, I’ve been tracking this issue on other netops mailing lists. There is a recent post on the LACNOG list from Leandro Bertholdo referencing https://datatracker.ietf.org/doc/draft-chen-ati-adaptive-ipv4-address-space/, a draft proposing another way to make additional IPv4 address space available. I haven’t had time to read the draft closely, but I noticed that it involves the use of 240/4. Subsequent googling about the draft turned up a presentation describing how the techniques described could be deployed. I noticed that the presentation made reference to OpenWRT, so perhaps the authors are aware of the work that the authors of the IPv4 Unicast Extensions Project have done in that area.
The adaptive-ipv4 draft will expire sometime next month, so anyone interested in seeing it move forward should contact the authors.
