Daniel, getProxyUrl works fine on orkut, hi5, netlog, friendster, and every other site I have buddypoke on. It's a great feature, and works very different to regular makeRequests. makeRequests are typically cached for, at most, a couple of hours. getProxyUrl typically uses the container's cdn (or similar) to store *static content* for really long periods of time - like a year. IMO it should definitely *not* be dropped from the spec..
