I think there are two main design dimensions, with a low-level and a
high-level for each of them:

1) Request processing flow abstraction
The low-level is dealing with raw socket connections and request/response.
The high-level is dealing with "calls" (unification of request and response)
or even "contexts" (calls + environment info/services).

2) REST/HTTP semantics abstraction
The low-level is dealing with persistent connections, pipelining,
reading/writing. The high-level is dealing with resources, representations,
content negotiation, etc.

See the attached illustrations for a tentative scoping of the JSR311 vs
Restlet and Servlet.
