does anyone know if anyone has worked on an ftp proxy program which talks
ftp to the end-user client and http to squid?

Even better would be some sort of inter process communication which
allowed other proxying programs to ask it "hey squid!, fetch this file
for me from this site". This would need an IPC spec for squid and an
ftpget which (optionally) returned native ftp rather than html.

this would be very useful:

    - ftp data would be cached by squid (which makes a lot more sense
      than having a squid cache and some hypothetical caching ftp proxy)

    - transparent proxying on linux could be used to automatically
      divert all ftp requests to the proxy.

anyone worked on anything like this?
