One of problems is that DeleGate try using UDP/SOCKS5 even when
no SOCKS server is specified.  This bug will be fixed with the
enclosed patch.
More serious one is that DeleGate does not support any recent
protocol of CU-SeeMe.  I could try it but I don't know whether
there is any public document about the protocol, in form like
RFC or Internet-Draft.  I feel it difficult to suport protocol
without the specification available freely.
