A "postmodern smart phone" should use whatever resources is necessary to provide its user with the performance and security the user requires. Today, my smartphone has 512MB of RAM. The FreeBSD server I use to run a validating resolver also has 512MB RAM. My FreeBSD server actually has less non-volatile storage than my smartphone.
The issue of device capacity is a red herring.

The future smartphone network you're imagining is one in which "clear path DNS" is disallowed while a secure channel for stub DNS RPC with magic OPT RRs is allowed? Really?
You want ubiquitous DNSSEC? Get it out of the server ghetto and get it mainstreamed and actually useful on devices non-geeks use. Coming up with new secure channels just means new ways in which folks who want to control resolution will break things.
