The reason this is still sitting here is because it's very difficult and requires heavy kernel modifications to software that we don't develop or maintain. At the typical rates that kernel developers command, this is a several thousand dollar project at a minimum, possibly into 5 figures, if we could even find someone willing and able to take it on. Of our existing developers, they either don't have the expertise, or don't have the time even if the money was there.
I'd love to see this happen, but the reality is we'd need at least 10 times what has been offered here to interest anyone capable of doing this kind of work.
