Maybe a bit off-topic, but I want to emphasize that the transparent
proxy facilities in the Linux kernel are developed to enable the
development of user-level proxy servers (only).
Any relation to the masquerading facilities is "purely accidental"
(sounds like a real disclaimer, isn't it? :-)).
I didn't completely follow the discussion about this topic, but the
idea of kernel-level transparent proxies that came up recently certainly
has no relation to the generic idea of transparent proxies: the latter
provide additional functionality, like authentication, filtering and
selection, caching, logging, etcetera (that's why a proxy is needed),
things that a "kernel-level proxy" could never provide.
