Re: [sig-policy]the size of sparse allocation

[Jeff Williams <jwkckid1@ix.netcom.com>]

Paul and all,

  Why is there a need for a sparse allocation policy at all?  And
from  your comments below why is there a need for arbitrarily
compare an allocation for the IANA vs an RIR/LIR or for that
matter a ISp?
