natd and PPP+pktAlias support it.  You can look at the code there; it
works, though it is a bit of a kludge.  There is no actual standard
for DCC - everything is defined as 'the way ircII works'.

There are some documents about the protocol at ftp.funet.fi, but
they're somewhat dated.

(And no, I don't know of any other proxies that support it, though
there probable are some.)
