Powerpoint Event Handling using VBA

Hi all
I am trying to do Application Sharing (Powerpoint) using VBA, For that i want to send what i am typing to my client system. I want to capture keypress or any of the key events. can anyone help me to achieve this.
Actually i am broadcasting messages to clients when the events occurs in the server using UDP Multicast. I dont have any problem in doing this. The problem is i need to see what the server is typing . If it is not possible in VBA is it possible using VB
