Skype status icons not visible from remote computer


As reported by email by Kirti Suri (Batchmaster Software)
Now when I acess the Sharepoint site on the development server where I have installed the .bar file and see site users(webpart) it shows the skype Icon next to the name of the users. Please refer to the attached screenshot 1.

While, when I acess the Sharepoint Site from a client machine and I login with skype it does not show me the online Users in Site User Webpart. I wonder where am I going wrong?
