Is the skip the number of pages, or the literal item count to start on?

Also, we would want a way to get back a total #, and page #'s give a page size.  This may be a separate call - wdyt?

Where would you override this?  In the pipeline creation?

Also, and opinions on using matrix parameters instead of query parameters?  For now we would need to combine with #PathParam & PathSegments.  See http://docs.jboss.org/resteasy/docs/3.0-beta-1/userguide/html_single/index.html#_PathParam_and_PathSegment for details.

This would allow future nesting of queries.
