I guess it depends on where you draw the line in deciding what 
constitutes a server. For example, in the scenario you outlined in 
response to my suggestion that the AF draft should define and require 
support for at least one URI scheme for identifying attachments you 
wrote:

In that case the service above could be thought of as a server that 
supports GET semantics. It could even provide support for content 
negotiation if that was desired.
