I'd recommend turning the data into GeoJSON on the server, then using a
Vector Layer with the HTTP Protocol and the GeoJSON format
(alternatively, a GML Layer with a GeoJSON format). If you really can't
do that, then you could write a custom subclass o the JSON format,
basing it of something like the GeoJSON format, and follow either of the
above options with your custom format.
