I thought Christophe made a good observation about our definition of 
"technology" [1] and I wrote a proposal to incorporate that [2]:  "Content

I haven't seen discussion of it. Are we totally off or did people miss it?

For an explanation, here's a resend of my last email (at [2]):

Good catch. Although, I think by ensuring the content works with user
agents, we ensure that the interaction between user, assistive technologies
and user agents is through protocols and APIs, so I think we can leave it
as "user agents."

Building on Neil's proposal:
Content is able to work with current and future technologies

What if we said:
Content is able to work with current and future user agents, including
assistive technologies.

Even though our definition of user agents [1] is borrowed from UAAG 1.0 and
includes assistive technologies, in other places in WCAG 2.0 we use
"including assistive technologies" to avoid confusion.  I'm happy to leave
it at "user agents."  if others feel that is more appropriate.
