I agree that it makes sense to capture this as a Web architecture
principle, though I am less enthusiastic about the chosen name.
It doesn't seem very expressive, and would likely be confused with
other similar-sounding principles:

  o Principle of Least Effort

  o Principle of Least Action

  o Principle of Least Authority

  o Principle of Least Privilege (a variant on Least Authority)

Oddly enough, the "Principle of Least Authority" comes closest
to TimBL's description of Least Power: "we ought to part with no more of
our rights to life, liberty, or property then is necessary for  
to preserve those rights from each other."

OTOH, Least Power also appeals back to the Declarative vs Procedural
debate in general.  Perhaps we can learn something from other sites
discussing that topic.

     Declarative Metadata Processing with XML and Java

     Declarative vs. Procedural Knowledge Representation

     Towards a Theoretical Base for Educational Multimedia Design.

     It's about procedural vs declarative, not just syntax

     Business Rules, Meta Data and Late Binding

In summary, I like the idea of expanding on this principle of
least power, but would prefer a more descriptive name.  OTOH,
since I haven't been able to think of a new name, I am happy to
continue using this one until a better name presents itself.
