Well, I can't join you, but I do have an "outrageous proposal" to throw into the mix.  Addresses should be allocated for finite periods of time and then removed from service for a while.  A specific form of this idea is for each address to be valid for a ten year period and unusable for six years.  A four bit portion of the address identifies which ten year period applies to this address.  Interfaces would generally have two addresses at any time, with the newer one five years fresher than the older one.  

This scheme forces constant renumbering at a slow, steady and predictable rate.  It will reclaim and compactly the address space, and it will engender more automation in the address assignment and management area. 

It's pretty easy to implement, but, of course, it's "outrageous."

It's probably easiest to just congregate somewhere and make plans there. The default "hang around at the reception area" won't work too well after 15.15 hours today, so I'm taking the liberty of suggesting the bus stop at the Markt square around 19.30 hours tonight, wear your badge for easy identification.
