I don't think the inability to SWIP addresses will in any way affect the
behavior of any monopolistic telco.
And as such, I think the telco vs SWIP issue is a red herring.
I agree that entities allocating prefixes to customers without
consideration of the needs of customers, will harm innovation (and
I do not agree that it is the business of ARIN to attempt to curb
monopolistic abuse - there are much better places, and much better
equipped organizations, for that kind of activity (e.g. FTC, FCC, DOJ,
etc. in the US, and similar organizations in the other ARIN countries.)
And, considering that I already gave an example of how SWIP of a prefix
/N, regardless of the value of N, is an activity that could be
considered not only valid, but necessary, I have to emphasize that I see
this as important for support of non-trivial deployments of IPv6.

Forcing specific sizes of end-use *within* a site, flies in the face of
allowing sites to use IPv6 as they see fit.
