Help with remoting

Hi

I'm having problems finding an easy description of remoting. Im not quite sure of what it even does.

I want to have a program that can send and integer value to another program and i was told that remoting was the way to go.

Here is what the application should do:

In a network there are two computers. The program on computer A is a check in application and when a person checks in, it needs to to send an integer value to a different program on computer B. The program on computer B then uses this integer value to show a few things.

Both programs know each others IP adress and both programs is being written in VB2005.

Any ideas
