I search for two programs..., Chat and file transfer Options

[Cobra]

I search for chat program. It must be:
1) SIMPLE, just type IP/HOST of another system and connect. Must work on internet, not only LAN.
2) SECURE, no message history, support for encryption and/or working with ZBD (look below).
3) TYPE-AHEAD function is a very good idea (like in Wintalk, ICQ chat, Epop (>BEST< LAN chat utility - www.wiredred.com)).

Just like discontinued Wintalk (http://tracker.5star-network.com/download?key=wintalk&uri=http://5star.freeserve.com/Internet/files/wtalk127.zip&site=1)
but must work on internet and be secure.

===============================================

I also need file transfer utility. I want to share my files with certain persons, but these persons have poor internet connection, so compression is needed (ZBD can handle it). FTP uses 2 ports and cause many problems with ZBD (look below).

"Zebedee is a simple program to establish an encrypted, compressed “tunnel” for TCP/IP or UDP data transfer between two systems. This allows traffic such as telnet, ftp and X to be protected from snooping as well as potentially gaining performance over low-bandwidth networks from compression."

Neil Winton, author of ZBD told me (in e-mail), he`s considering at the moment to make the
encryption and compression algorithms "pluggable" -- to allow different algorithms to be
added easily. But he haven't done this yet.

I think, there are many good coders on this forum, maybe someone can help developing ZBD.

I don't know much about Jabber, but it's worth checking out perhaps
