Actually, you don't even need squid on the other end.  All you need is
to make ssh use its DynamicForward:

$ ssh -N -f -D 1080 remotehost

And, bam! I have a socks5 proxy tunnel from your localhost to the
remotehost.  Any application that can use socks5 (firefox, xchat, gaim,
etc) can now use the tunnel to connect to anything through the tunnel
and from the remote host.
