Looking for ASP.NET Facebook Style one to one Chat for my social media site Ajax based?

We have a requirement for a one to one chat from one of our clients for a social media kind of project we are doing. The problem is that we need it in quick time so i would rather use an already made component that is out there. I do not mind paying a license fee but it must not be a yearly thing. One time fee is something that we can convince our project lead for. I have been searching google for the past 4 days and i do not see any components similar to what we need in asp.net. I do see comet chat for php but we need that in asp.net.

below are some of our main requirements:

1-1 chat Footer placement in bottom right similar to that of facebook and gmail. The ones i can find right now are all chat room sort of layout which we cannot do. Status to be changes by user. Appear Offline is a must. SQL Server Database. We need all chat transcripts to be saved until we want to delete/archive them. Group Chat is a plus as we might need that in future but is not needed right now. But a possibility of having in future would be a good thing.

Any help/suggestions will be highly appreciated.

Below are some links that I think might help you. In these links they are talking about the same thing you have mentioned and they have posted some good solutions. Also I have mention a URL which I think is the asp chat component you are seeking.
