I need to exploit the transparent proxy support in Linux.
However, this requires the setting of a non-standard option
(IP_TRANSPARENT) before a socket is bound.
To achieve this, it seems to me I have to implement a
SocketImplFactory to instantiate a custom socket implementation.
And my custom socket implementation cannot extend PlainSocketImpl
because it's not public.
So I'm faced with having to write a significant amount of code to set
on a bit.
Before I go too far down the route, I want to check whether there are
any openjdk initiatives that might simplify this sort of activity at
some time in the future.

You might want to look at java.nio.channels.NetworkChannel for ideas.
You'll see that it defines the setOption/setOption methods and so isn't
restricted to the standard socket options defined in the javadoc. Some
day it might be good to retrofit classic
Socket/ServerSocket/DatagramSocket with methods like these. That way an
implementation could support additional and platform specific options.
