I really see no reason to change it at all. "machine-to-machine" does not 
imply
physically separate and distinct "machines" (boxes); it is meant to imply 
that 
the interchange does not require human involvement/intervention at 
runtime.

I suppose that "application-to-application" might eliminate any confusion 
that
the definition suggests that machine=box and that it was only intended to 
support the case where there were two (or more I suppose) physically 
separate
and distinct boxes.

Application-to-application might be acceptable, but application is also 
fuzzy;
isn't a browser an application (or is it just part of the OS:-).

Maybe it would be clearer if the definition read:

A Web service is a software system, designed to support
interactions that do not require human involvement at runtime 
between agents over a network, ...
