Well, I tried it (at work no doubt) and we are behind a firewall. I was talking to my other half and needed to pull a file from my computer. She is not very computer savvy, and did not want to frustrate her in getting the IP. I did however talk to her on AIM. Tried the program, I don't know if it because we are behind a firewall or what, but I could not get my IP. Please tell me I am missing something! (my ISP will not give out static IPs anymore, otherwise, this would have never been an issue.)
