How about this (mostly copying RF's text):

   The World Wide Web is an information space consisting of
   resources that are interconnected by links defined within that
   space.  This information space is the basis of, and is shared
   by, a number of information systems, including the
   "traditional" Web and emerging technologies such as Web
   Services and the Semantic Web.  Within each of these systems,
   agents (e.g., browsers, servers, spiders, and proxies) acting
   within diverse networks provide, retrieve, create, analyze,
   and reason about resources.

   [Rest of abstract is RF text, though I may split into paras]

This captures the "over the Internet/other networks" part in
"acting within diverse networks". Later, to capture the "network/graph"
aspect, we have in section 2 already:
 When a representation of one resource refers to another resource with 
 a URI, a link is formed between the two resources. The
 networked information space is built of linked resources, and the
 large-scale effect is a shared information space. The value of the Web
 grows exponentially as a function of the number of linked resources
 (the "network effect").

Is that enough to capture Roy's point?

We currently have a section on Hyperlinks in the Representations
section. Some of that TB is referring to (I think) is discussed there.
For now, I will try to introduce RF's text on links into that section;
we can decide to move it at the ftf meeting.
