NS delegation works for exactly one provider. This is probably just
fine for a pretty reasonable swath of small business, but it really
doesn't addresss the whole spectrum. For example, if I outsource my
mail to isp.com, I'm also pretty likely to outsource my email campaigns
to advertisomatic.com too.
Right. I wasn't really trying to address the whole spectrum. The
suggestion is that the common case is not as hard as it seems some are
saying. More importantly, the common case need not involve third-party
signatures.
like there would be some advantage to do the indirection at the protocol
layer (eg, SSP) rather than at the DNS layer (eg NS).
Sure, in this scenario you need a multi-indirection capability,
regardless of the technology you use. But is this saying anything more
than complex requirements require complex deployments?
The more general question I guess is how much do we want to get into
defining management mechanisms? Largely I'd think such things don't
require standardization and might benefit from a competitive
landscape.
Mark.
