Can anyone suggest whether there is market for products like LAN messenger or Intranet Messenger. I mean if i develop a product containing all the major features more focussing on the greater ability of video conferencing or desktop sharing then is there is a chance for such product to get a successful boom in the market? Becuase for voice conferencing I know the skype is the best but really i can't find any such messenger which has greater ability to give a more comprehensive dektop sharing or video conferencing.
