I think that when we consider SWIP boundaries, we should take into account 
strictly technical considerations, and not arbitrary ones.  I think the 
argument for requiring a /48 or larger to be SWIPed is well-grounded in 
network engineering practices.  I'm not sure I understand the technical 
argument for anything smaller than a /48 being mandatory.

Thank you,
