Populate a listbox with all of the names of the computers on the server & their logged in users.

Send a packet to another program (that I have also written) on another networked computer.

How to send packets of data to multiple other computers (cannot tell how many there are).

How to convert music data into string kinda data, stuff I can send over the net.

Thanks All
