Audio-Video messenger working with Windows Live for Linux

What is needed in this project is an Audio-Video plus chat Messenger that is able to connect and be used as an Windows Live messenger but to be able to run on Linux OS. Exact info: you can say a clone of Live Messenger for linux by this i mean. Audio-Video Conversation working not as individual but through live messenger service the how is up to you you can either get in through the contacts of live messenger (hotmail etc etc) and make a video-audio thats work by using this contact and through the wndows live service or just get the contacts and make the audio-video through another service but give false idea it is working by this Messenger YOU have made. The rest i believe is normal chat, offline messaging ... etc etc whatever the live messenger has. For more info please send me whatever questions you have. Thanks in advance ## Deliverables I hope it is detailed enough for more info pls dont hesitate to contact me.
