Know also there are remote hardware devices that will take a CW paddle and interface it to your remote PC.
Note: None of these programs or devices are going to be particularly easy to set up and make work. You need to have a very good understanding of TCP/IP networking protocols and routing and TCP/IP ports and port forwarding etc. If you don't have these skills, then you will need to enlist the help of someone who does. In other words, how good is your geek?
Since you didn't find any of these things on your own doing simple google searches, I suspect you may need some help. And you need someone to help that can devote hours to debugging and making things work smoothly. Ideally that would be you, but if not you, then you will have to have a dedicated person to assist you. That person is called a Geek.
Good luck and let us know how you get along.
