the people that complained the most about variable length addresses were the host people
in particular Jim Bound

the router people (Tonl Li and the rest of the gang from Cisco for example) pushed hard for 
variable length

we did have a variable length proposal right at the end of the IPng process

but that did not achieve escape velocity
