Proxies are generated at compile time. Here ozone just substituts datbase
object and corresponding proxy - at runtime.

Yes. Would probably be much slower than the current solution and runs only on
1.3.

When I want to present an ozone object in the browser then I convert it to XML
(xmlForObject()) and pass it through a XSLT processor (I'm using Cocoon and
Infozone/Prowler but this is not a must). This works great, simple, fast.
