Has anyone written a nice chat component that shows the conversation in a scroll?

Just wondering if anyone has already written a “best of breed” UI chat component I can just into my existing app?

(Why re-invent the light bulb?)

I guess it will have to be me!

I have seen several implementations out in the wild (one was made by me), but none of those were public. Or “plug 'n play ready”.

Good luck and don’t forget to share!
