If you are already doing it over the LAN/WAN, then you already have 
everything in place to do it over the Internet as well, as far as your code 
is concerned.  It is just a matter of which IP address(es) you connect to, 
and whether you need routers/gateways installed in between to reach it/them.

Interesting...Interesting indeed!
Is there any "Public" server i can use for a test?...I mean to test my code before I set up my own server? and what about the authentication issues? doesn't one need to identify ones self before getting access to an internet server?

To be more specific, I would like to use Sametime Lotus Notes server to chat using my App. If I use Lotus Notes Sametime Connect application, I provide: sametime server name, User name and password. Now I need to develope my application and do the chating instaed of the applicaion supplied by lotus....assist please.

No.  You have to set up your own server for that, since only you know how 
your chat protocol works.

You have to implement that in your communication protocol.  Your clients 
have to identify themselves when connecting to your server.

Another thing is the architecture of the application

1. Pier to Pier - This is where you connect directly to the other 
party's computer. One of you will need to open up some ports (or one 
port) for the traffic to travel . Open up means that allow to
receive incoming TCP/IP connections.
This means that one is the client and the other the server.

  CLIENT ->---------------->- CLIENT (listen mode)


2. Through a Central Server.
This is where a central server is sitting on the internet and
is wait for connections. Once a connection comes in it will be registered
as one in a chat session or chat room. Then another connects to
the server and registers as well and then the both parties chat
though the central server.
The advantage is that the clients do not have to have TCP/IP ports
opened up. The disadvantage is that it is more complex.
Matter of fact this architecture is how most chat servers do their
thing even yahoo chat, msn, etc..
CLIENT ->------------>- SERVER -<-----------<- CLIENT
