If your friends and family are running limewire and your host can accept incoming connection they can complete the following steps to connect to your node.

1. From the connection tab type the IP_ADDR in the appropriate field and click ADD. In your connection tab you should see a connection to your host from their ip address.

I think this will do it. I've heard people suggesting it before but I personally don't know if it works or not.

If you have any problems let me know.

Hope this helps.
