Dumb Question

1. Clients can talk to your IP but not to 'localhost'. Local host is 127.0.0.1 which is a local looback IP on every computer..and I believe none routable on a network. Your computer, if it is on a network should have another IP address.. type: ipconfig in a command window to see the IP.

Assuming you have highspeed internet, you need to figure out the IP of your connection (ie. http://www.whatismyip.com/). Then you need to setup the firewall to forward connections to your IP on the network or put your computer in the demilitarized zone with a dedicated ip if you can (big security risk).

You'll need the client application of course to have a way to determine your IP such as embedding it in the application. This can be a pain if your service provider changes your IP address at random.

And somehow you need to distrubute the client application.. perhaps embedded in a web page on your website or an adobe air download?

2. A better program? Depends what your requirementse. If you only want simple video/voice and text chat you could use Windows Messenger. And I think the latest or beta version of Skpe has video as well.. but I'm not a skype user.

And they are no stupid question. There are only stupid mistakes made by not asking the question.
